comments on new PDB galleries on gene pages

Any comments/suggestions for the PDB gallery prototype on

talk
) 20:08, 25 January 2009 (UTC)

Looks great! Of course, some upper limit needs to be placed on the number of structures displayed per article (~10?). If the number of available structures exceeds this limit, ideally the structures selected should be:
  • most informative (i.e., largest fragments of the protein, include biologically relevant co-factors, endogenous ligands, highest resolution, etc.) and
  • maximally diverse (e.g., making sure that at least one structure from each of the available domains for multi domain proteins is included)
but it is probably not possible to automate this. Lacking any automatic mechanism, if all the structures EMBL-EBI are uploaded into Wikipedia, then editors could manually change the selection if needed.

Yes, I should have mentioned that this is part of a parallel project to load images for all PDB files into wikicommons. I'm very interested to hear how people think we should handle gene for which there are many structures (e.g.,

I hadn't thought about javascript show/hide bars. That would be an elegant way of handling the problem of band width and screen real estate. However this doesn't address the more fundamental issue of what the purpose of these graphics is. The first figure added has very high value, if for no other reason to add eye candy to entice the viewer to read the rest of the article. In addition, one representative figure gives a quick impression of the tertiary structure of the protein (i.e.,

I like it, let's set an upper limit (say five?) and let human editors expand/replace as necessary. As a default selection, how about we choose the five longest sequences? (I think we can easily get this...) Unless there are any structural biologists in the room who have a better idea of how to define the criteria for "most useful"?
talk
) 22:19, 26 January 2009 (UTC)
Five as an upper limit sounds reasonable. However instead of choosing the five longest sequences, it might be better to choose the longest, the shortest, and several in between. In the case of PPAR-γ, choosing the five longest would select three holo structures, two ligand binding domain (LDB) structures, and no DNA binding domain (DBD) structures. Using a sequence length spread would increase both the diversity of structures displayed and the probability that structures representing all of the domains were displayed (e.g., holo + LBD + DBD). I noticed that you included the SCOP classification with each of the structures. Perhaps this could be parsed in order to make sure that each of the available domains were covered, although this may be misleading in the case of structures which are complexes of two or more proteins. Does the procedure used to select the SCOP classification insure that the classification is based on the protein of interest and not other proteins that may be co-crystallized with the target protein? Ditto for the calculation of the sequence length.

I agree with
Boghog2 on picking a diversity of domains if it is possible to automate that. I also wondered, purely as an asthetic thing, whether the label under each image may include the protein/domain description rather than just a PDB accession number? ~ Ciar ~ (Talk to me!)
23:46, 26 January 2009 (UTC)
If some structural biologist can propose a reasonable way to pick diverse examples, we can work on implementing it. But, this may be a difficult enough problem to require human intelligence. On the label issue, I'm happy to label it with whatever field we decide on. The challenge is figuring out which one, as most relevant fields are quite long. Check out [1] or [2] (and links), for example. Do you see a field you think would be appropriate? BTW, anyone is free to play around with

H'mmm, just looking at these 2 examples, what about (under the PDB header link) the line beginning
"COMPND 4 FRAGMENT:""
I don't know if this rule will hold up in all the PDB files, but maybe the text following "FRAGMENT:" could be grabbed? The actual protein name won't be needed since the entire page is about one protein. What do you think? ~ Ciar ~ (Talk to me!) 02:47, 27 January 2009 (UTC)
Sure, that seems like a pretty good idea. Just heading out now, but I'll try to mock that up tomorrow... Cheers,

My preference would be to use the PDB TITLE field for the figure caption. The title field contains other potential useful information (e.g., experimental method) and also information about the domain (although less detailed). A complication with the FRAGMENT field is how to handle heteromultimeric structures such as PDB: 3dzy​. In this particular example, there are two fragment fields which are difficult to interpret without also looking at the corresponding MOLECULE fields. For this structure, one would need some how parse and combine four different fields (two fragment and two molecule fields). It would be much simpler to use the single title field.
I have taken the liberty to add the PDB title fields to the figure caption in the

) 15:18, 27 January 2009 (UTC)
I was worried that the title field would be too long, but I actually like how it looks now. Multi-line caption doesn't bother me at all, and it gives a bit more context that might bring the gallery beyond eye candy. Nice! Do you all think we should still look at the hide/show bar, or not?

Hello, I've prototyped two more gene stub enhancements for comment. The first is shown here, which adds a section for well-established protein interactions.

Estrogen is the one where I stumbled over it this time, but I've had this before in other cases. The medicine bunch seems to be good enough at covering topics concerning humans.

3 weeks of biomembrane madness

I have been recruited by a professor at the University of Florida to assist her graduate-level class to get GA level articles in the topic of their choice. Each of them gave a PowerPoint presentation primarily of visuals and oral explanations. The professor then asked them to translate their presentations into Wiki articles. They don't necessarily have a lot of time to nominate their articles for GA, so the instructor is going to assess their articles and grade them on how close they get to GA criteria. They are, however, urged to nominate their articles for GA even though they may not be in the class by the time it is reviewed.

I gave an hour-long presentation in their class today on the very basics of editing and Wikipedia. The class has a

Using figures from scientific papers

What is the policy with regard to using figures from scientific papers on wikipedia? I noticed that on carboxysome the images have been taken from papers and are licenced under the Creative Commons Attribution 3.0 Unported licence. I'd like to add similar images to acidocalcisome from the referenced paper - can I just copy it and use the same licence? Do I need permission from the paper's author?

You can't use the figures without the copyright holders releasing them into the public domain or under a Creative Commons licence. The exception is the

Proposal section "Possible merge of wikiproject cell signaling to this project as a taskforce"?

I made a proposal on the proposal section of this talk page here: [7] and I assume not many have had a look at it and/or don't mind either way. If anyone wants to comment, feel free to do so. Also see this [8]. I would be more than happy to do all the merging, I just want to make sure I am not going to annoy someone by doing it, or if anyone would think there would be no point to do so and leave everything as it is. Cheers!Calaka (talk) 04:09, 16 May 2009 (UTC)

In addition to the above, I think the same would apply for
Wikipedia:WikiProject RNA. Hence we can create something similar to the set up of WP:MED where they have a task force page linking all the task forces and the ability to suggest new task forces in the talk page. Hence this project would have 3 task forces to begin with and any new suggestiosns can be made there. I will post a little note on these 2 other projects as well. Calaka (talk
) 03:45, 23 May 2009 (UTC)
In principle, I don't have a problem with this idea. I know WikiProject RNA hasn't been very active recently. In spite our pleas to the RNA community. However, I don't see the advantage of a task-force of MCB versus a daughter WikiProject of MCB. Can you give some further justification/motivation?--Paul (talk) 19:59, 23 May 2009 (UTC)
I would be happy to. Having said that, I will not get angry if there is no push for forming the above into task forces, it was just my oppinion of it being a better way to go. So some reasons I would suggest include:
  1. There will be only one talk page template and would reduce the amount of templates that are to go on one page. Example: Instead of Talk:Cytokine having 4 tags (one for WP:MED, one for WP:MCB, one for WP:Cell signaling and (well I think it should have) one for WP:metabolic pathways), it can just have two, the WP:MED one and the WP:MCB one where there can be an indication of the task forces associated. So the tag would look like this: {{WP:MCB|class=|importance=|cell-signaling=yes|metabolic-pathway=yes}}. This is allready done in many other wikiprojects such as the videogame wikiprojects, military history and of course WP:MED. Examples for each respectivelly: Talk:World_of_Warcraft, Talk:Battle_of_Iwo_Jima and Talk:Dermatology.
  2. There will be one list of participants. They can then select whether they want to be associated with that project or that one, instead of having to write their name each time they want to join a project. This leads on to point 3:
  3. There will be larger activity/discussion on the one talk page (i.e. this one right here) for an overall discussion about certain topics. I.e. if they wanted to talk about cytokines, they can bring up the discussion on this page, which will get the most attention and it applies to all things that they might be interested in. Having said that, there will be nothing stopping them from discussing this in their own task force talk page, but as I have noticed on WP:MED talk page, there tends to be the most viewership/discussion on the one main page. Leading on again from this is point 4:
  4. Users can watchlist only one talk page, instead of having to watchlist one for every wikiproject. So they can focus on this page to discuss, while they can check up on the others less frequently.
  5. In terms of organization/hierarchy, it would be better to have everything under one "umbrella" so to speak so everything comes out under the MCB link. I.e. I have personal trouble finding wikiprojects of a specific nature (e.g. I have trouble searching for devil may cry wikiproject, but wikiproject video games was very easy to find). In this same regard, having MCB as the parent which then directly links to the taskforces increases their exposure c.f. seperate wikiprojects where users might feel overwhelmed with joining other wikiprojects because they think they will be having too much to handle. In this way, it will seem that the projects while not appearing as LARGE, also seem more accessible to them.
  6. This in no way reduces the value of these wikiprojects. Just because they are classified as task forces, does not mean that they reduce their importance that they play in encouraging collaboration between users of a certain interest.
  7. Following on from step 3, the more users in one wikiproject would just be better in general. I will give an analogy: Imagine 5 very very large cities. They are extremelly large in area, but have a small population density. While they might be big in themselves, they are after all quiet due to not having as many people in them. Then think of Singapore. It too is a big city but it has an incredible amount of people in that space! So imagine they had their own little metaphorical talk page. Just by numbers alone, you can imagine/predict there would be more activity in the Singapore talk page than in the 5 individual cities individually or combined. More discussion would lead to more activity and more activity to hopefully more creation/collaboaration in improving the wikipedia articles of interest (in this case MCB type ones).
I had more thoughts, but at the moment they escape me. When I think of a few more I will add some here. If you want, feel free to look at this here: Template:WPMED_Navigation and here Wikipedia:WikiProject Medicine/Task forces which also states reasons on why they chose to go in the "task force" direction. I should have looked at that page first before I wrote all of the above hehe! To make things easier though, we wont be recreating the wheel, but will just take the ideas from the WP:MED people and follow their guidelines in going through this whole process.
At the end of the day, it is my hope that this process of wikiprojects-->taskforces will lead to more activity & hence more editing/working on these articles. Thanks and again, all comments are welcome. Calaka (talk) 04:09, 24 May 2009 (UTC)
I like this idea, mostly since it will make it easier for new editors trying to find an active talkpage to ask questions on. Tim Vickers (talk) 14:39, 24 May 2009 (UTC)
Makes sense to me - it looks stupid having loads of different wikiproject tags on talk pages. I agree that it would also help in aiding discussion on talk pages. (Correct me if I'm wrong) but this project isn't exactly busy at the moment - after all it's a sub project of biology really - so having another tier of projects below this doesn't make sense to me.

I will give it a few more days (perhaps until June first?) in case anyone else has any other comments to make and I will do incremental changes (i.e. I will move one wikiproject at a time, make sure it is moved correctly, then go over the next one after a few days, I guess there is no rush in this process). I guess this wikiproject might not be as active as it can be (or as it has been), but with time it should grow and with this addition of the additional task forces, it might lead to an increase in activity.

Well actually, this project (MCB) seems really inactive to me too... sounds maybe weird for such a big project with so many articles and members.

Membrane receptor

A project in a North Carolina university adopted

membrane receptor, added a lot of valuable material and then abandoned it again. I have tried to put some Wikipedia touch to it and think it is now rather good.

I can help. The first thing I noticed is that the
membrane receptor page has a red link to Category:Receptor tyrosine kinases, but other pages such as Receptor tyrosine kinase use Category:Tyrosine kinase receptors. According to my search of the NLM's PubMed data base, "receptor tyrosine kinase" is used more than "tyrosine kinase receptor". --JWSchmidt (talk

Aminoacid structure formulae

Hi, I've been browsing the amino acid articles lately, and I noticed the lewis formulae lack a consistent style. At least for those amino acids that allow it, I think it would be a good idea to implement some basic guidelines, like having all structural formulae horizontally aligned, with the amino group showing down and the carboxyl group showing left. This seems to be the tentative standard for most amino acids - take Cysteine or Glutamine for instance if you want to see what I mean. However there are some which do not yet abide to this rule, like say asparagine. Also some α–amino acids show the hydrogen atom bound to the α–carbon, which is redundant even with respect to isomery, since the position of the C-C bonds unmistakably indicates that of the C-H bond.

That being said, I find this would be a considerable improvement, and I would gladly take care of it myself, but I lack any knowledge of how to produce lewis formulae save for painstakingly drawing them out with the gimp :-/ —Preceding unsigned comment added by Chymæra (talk • contribs) 18:29, 30 May 2009 (UTC)

    • This includes a new interface for making requests to add a new project to the list.
    • There is also a form to request a change to the configuration for a project. Currently the configurable options are the size of the on-wiki list and the project subpage used for the list.
  • The on-wiki list should be generated and posted in a more timely and consistent manner than before.
  • The data is now retained indefinitely.
  • The script used to generate the pages has changed. The output should be the same. Please report any apparent inconsistencies (see below).
  • Bugs and feature requests should be reported using the Toolserver's bug tracker for "alexz's tools" - [9]

Organism groups ???

I notice Bacteria in the trophy case. It is not reasonable to consider each taxon a part of MCB. So how do we choose to include some of the taxa? Some have been especially important in MCB research. Sperm whale in studying the structure of hemoglobin, Humans because this is the subject of Medicine, Drosophila melanogaster for early chromosome studies etc. But I can't see why bacteria should be more central to MCB than animals or plants. Because they have only one cell each? Well isn't there more MCB when there are more cells? ... and bigger more complex cells? To summarize: What are the legitimate criteria for including a taxon article in MCB? --Ettrig (talk) 07:02, 12 July 2009 (UTC)

I see your point, but I suppose I'd argue that the article does dwell in detail on bacterial cellular biology and biochemistry, since this forms a larger proportion of their biology than multicellular organisms. Classifications are not exclusive, and Wiki articles can be maintained by several projects, see Talk:Bacteria for the complete list. Tim Vickers (talk) 16:12, 12 July 2009 (UTC)

Help with Ku (protein) and redundant articles

Not sure what to do about this. There is an article on the Ku heterodimer, but there are also articles on each subunit, Ku70 and Ku80. Would it be best to have the individual subunits redirect to the heterodimer article, or should there be some brief text there along with a link? What is the standard when dealing with members of a complex when there's a separate article for the complex? Compounding the situation is the fact that Ku70 and Ku80 are currently redirected to old gene names that have not been used in the literature in years. Suggestions for how to deal with this? Thanks. Amazinglarry (talk) 21:34, 15 July 2009 (UTC)

I don't think there is a problem having separate articles about the complex and the individual subunits. I have added protein boxes to the parent article to make clearer both the old and new nomenclature. I do agree however that the present naming is both out of date and confusing. I propose that the three pages be renamed as follows:
  • Ku (protein) (XRCC5 + XRCC6 complex) → ATP-dependent DNA helicase II
  • ATP-dependent DNA helicase 2 subunit 2
    (Ku80, XRCC5) → ATP-dependent DNA helicase II, 80 kDa subunit
  • XRCC6
    (Ku70) → ATP-dependent DNA helicase II, 70 kDa subunit
Does this sound reasonable? Are there other suggestions?
talk
) 07:14, 16 July 2009 (UTC)
Thanks for your help. I think the article titles for the subunits should be Ku70 and Ku80, and the heterodimer can probably stay as it is. XRCC5 and XRCC6 were the names of the original CHO cell lines but haven't been used in the literature in over a decade. I'm not even sure where the "ATP dependent helicase" names came from because this protein is not a helicase (it is an ATPase though). Amazinglarry (talk) 11:43, 16 July 2009 (UTC)
The currently accepted official
talk
) 12:36, 16 July 2009 (UTC)
After further digging, the currently recommended UniProt protein names are:
  • P12956 – ATP-dependent DNA helicase 2 subunit 1
  • P13010 – ATP-dependent DNA helicase 2 subunit 2
The diversity of names is somewhat confusing. My bias would be to use the UniProt protein names in preference to HUGO gene names since the function is clearer from the protein names.
talk
) 13:13, 16 July 2009 (UTC)
I think it makes the most sense to use the name that is used in the literature. Nobody will ever find this article if it's under "ATP-dependent DNA helicase 2 subunit 1" because all of the hundreds of papers on it have been calling it "Ku" for over a decade now. People looking for information on this protein will be searching for "Ku". I feel that calling it by an archaic unused name from a database makes Wikipedia look out of touch with current research. Amazinglarry (talk) 13:31, 16 July 2009 (UTC)
Finding the articles need not be a problem. Just create redirect pages for all the names. --Ettrig (talk) 14:24, 16 July 2009 (UTC)

WillowW has done a fantastic job creating pages for enzymes which incorporate both the {{enzyme links}} and {{enzyme references}} templates. While these templates are very useful, I think they could be tweaked to make them even better.

As I see it, there are a few shortcomings with the present templates. First, there is some redundancy in that the IUBMB and BRENDA links are contained in both templates and also the EC number is displayed in almost every line of the template generated text. Second, they do not contain internal Wiki links which would give some information on the type data that these external links contain. Based on her work, I have created a new template {{

enzyme
}} (see the example to the right). This merges the information that is contained in the links and references templates and at the same time address the shortcomings mentioned above.

I am not suggesting that we replace en masse the {{enzyme links}} and {{enzyme references}} templates with this new template, but in certain situations the new template might offer some advantages when updating enzyme articles.

Comments and suggestions are welcome.

Phosphodiester bond

The article Directionality (molecular biology) is written not so clearly. Let me bring out a few points.

  1. The lead says

    The relative positions of structures along a strand of nucleic acid, including genes and various protein binding sites, are usually noted as being either upstream (towards the 5' end) or downstream (towards the 3' end).

    Since this is in the lead, I would expect this statement to be explained later on. That doesn't happen. Apart from that, I find it hard to understand what this sentence means. It seems ambiguous to me.
  2. We have here
  • 3' hydroxyl group
  • 3'-hydroxyl
  • 3'-OH group (in DNA polymerase)
  • 5'-phosphate group
  • 5'-phosphate
  • 5' phosphate
  • 5'-flanking region
  • 5' flanking region

In other words, no defined style as to the use of the hyphen and the word "group". I decided to write about it here because 1. the discussion page of Directionality (molecular biology) is empty and is likely to be poorly visited 2. this matter is likely to demand a general solution that would be applied over all articles of this WikiProject.

The current protein box displays, under RNA Expression Pattern, the results of one experiment (GNF SymAtlas), done on one technological platform (Affymetrix U133A). The Gene Expression Atlas provides data on RNA Expression Patterns from over a thousand experiments, done on dozens of different platforms - so, we propose an extended, more general view on gene expression patterns, composed from data from multiple independent experimental sources, as opposed to the specialized single-point-of-view information that is available now. We hope this would be a useful addition, more encompassing and not detailed... We could, for example, show tissue-level expression data or disease-level expression data to complement the GNF data, if that's viewed as informative. What do you think? ostolop 18:14, 11 September 2009 (UTC)
I think one thing we have to keep in mind is that it is more important to be clear than it is to be exhaustive. One reason I think the "Gene Atlas" barcharts are useful is exactly because it only displays one experiment, since that one experiment answers a reasonably basic question of "Where is this gene expressed in the human body?" Other less-universal data sets are hidden behind the link to More reference expression data. Perhaps one alternative to consider would be something like this: "More reference expression data (BioGPS, ATLAS)"? (Full disclosure: I have strong sentimental ties to the Gene Atlas data, which I think most here are aware of, but I don't think that is influencing my comments here...) Cheers,

Organism parts are outlined on the sketch of human body (derived from http://en.wikipedia.org/wiki/File:Human_body_features.svg), and numbers of experiments with non-trivial expression are displayed accordingly to legend. It is proposed to embed ATLAS template into GNF Protein Box, instead of editing each gene page. Please let me know your thoughts. Mus4musculus (talk

I like the visualization of the human body (and presumably the tissues highlighted would change based on the specific gene?), but I still don't quite understand the metrics. See my comment above (regarding up/down-regulated relative to what?). As another example of my confusion, I see the kidney has one up-regulated study on the BRCA1 page. But then I click the data in ATLAS link and see there that kidney has two up-regulated studies. Why the difference? Anyway, my overarching comment is that it is a bit unclear to me how users should interpret the infobox and data. Cheers,

You are right, images for all genes will be generated automatically with different set of features highlighted. As for data discrepancy, you probably looked up wrong gene, BRCA1 in kidney featured in 1 experiment: http://www.ebi.ac.uk/gxa/gene?gid=ENSG00000012048. Anyways, boxes to be re-generated as Atlas database grows, so number of experiments will change over time. About metrics - numbers in boxes are numbers of experiments where the gene is found over/under expressed, it is not a "number of conditions" as you said above (maybe that's the root of confusion?). Numbers tend to grow, they are not static. We do not treat numbers of experiments as a property of a gene, rather as an indication of content availability.
To answer your question "up/down-regulated relative to what." That varies somewhat from experiment to experiment, but in most cases it's safe to say - relative to the background made up by mean expression over multiple other tissues. For experiments like the GNF data set, over-expression in any one tissue is relative to the baseline level over some 60 tissues, and in certain other experiments the comparison might be relative to a reference tissue pool. In general concordance of activity over multiple studies indicates a more reliable finding. Thanks, ostolop (talk) 20:50, 18 September 2009 (UTC)
Okay, thanks for the additional clarification (and for catching my mistake with the wrong gene above). I think I'm starting to wrap my head around this now. One suggestion and one comment. First, I suggest that you might link the up/down numbers in the table directly to the specific experiment(s) that are up/down regulated. I think most naive users would look at "1/0", for example, and not know what to do with it. You'd be hoping that they'd scroll down to the bottom, and then be motivated enough to find their tissue of interest again on the gxa site. Better if they get the instant feedback of clicking on the number directly to get more info. My second comment is regarding your comment that "general concordance of activity over multiple studies indicates a more reliable finding". Since the comparison group changes for each experiment, I personally think it's tough to gauge how the numbers should be interpreted. Anyway, I'm interested to hear how others see this... Cheers,

The human body visualisation is cool! I found the 'Uterine Cervix' label on a male figure a bit of a surprise. The numbers below are difficult to interpret at a quick glance. The classification seems very binary. Isn't there a large class of genes with an indeterminate expression level -- ie. neither up nor down? Colored/heatmap human figures based upon a p-value would be ideal wouldn't it? It might be too difficult to implement however (and be frightfully gaudy).--Paul (talk) 10:44, 19 September 2009 (UTC)
I have a suggestion. I think the expression data should be displayed in a 2D array where rows correspond to different tissues and columns would correspond to three different conditions (normal, diseased, compound treated). The normal column would indicate whether that gene is expressed or not expressed (or perhaps a finer gradation: none, low, medium, high) in a particular tissue. The second and third columns would indicate up or down regulated relative to the corresponding normal untreated tissue in the same row in column 1. (I also would propose that any data from an immortalized cell line would be treated as a disease state and therefore included in column 2.) The data in this format would convey useful and immediately understandable information. The data as it is presently displayed in

On a somewhat related issue, both the GNF SymAtlas and Gene Expression Atlas contain mRNA expression data. For balance, it would also be desirable to provide links to protein expression data since the correlation between mRNA and protein expression is often not good and it is changes in protein expression rather than mRNA which normally results in a change in cell phenotype. One example data set may be found at the Human Protein Atlas (example: HPR:BRCA1).

It would have been great to add at least a link to the Human Protein Atlas if not a box (I felt like giving bot-coding a try when I first saw the suggestion). Problem for automated addition is, you seem to need the antibody ID for links and there doesn't seem to be system for getting from any gene ID/symbol; and the site doesn't allow database download. Narayanese (talk) 08:20, 20 September 2009 (UTC)
According to the Human Protein Atlas search FAQ: "In order to list all genes and antibodies, empty the query field and press the search button." Then on the upper right hand side, click on "Show search results: all". This will produce a table of all the proteins and antibodies in the database. The ensembl_gene_id is not directly visible in the table, however the antibody link is imbedded in the html source. For example: <a class="anti_link" href="tissue_profile.php?antibody_id=16673&g_no=ENSG00000121410">. So it is a bit messy, but we should be able to extract the necessary links from the html source.

Cool. I'm on it. Narayanese (talk) 17:24, 20 September 2009 (UTC)
I'm not fond of the box. Neither number of experiments or up/down how much to to with the biology of the gene. Especially when it's based on p values - picks up many indirect and irrelevant effects (which might be why there are so many conditions with both up and down for well-studied genes). I have a feeling that showing fold change like Andrew's project does has so much better chance of showing something meaningful. Plus the box is uniterpretable without reading how the numbers were made (there's a bit on the EBI site, didn't seem to be a link to a publication though). Turning it into a collapsed box might be a good idea, it's hard to fit into a page in it's current form. Hope I didn't get too rambling, it's late here.

I like the smaller font. I don't get what "subject" means. I would spell Pubmed "PubMed" and Refeq "RefSeq".

While I do like the new format, I just noticed one difference which in my opinion make the boxes slightly harder to read. In the old version, under the "Identifiers" and "Orthologs" section, the backgound was grey with thin white lines separating the rows. In the new version, the entire background is white which makes it slightly harder to distinguish between the subsections (Symbols vs External IDs vs EC number and Entrez vs Ensembl vs ... ). Hence I would appreciate if the grey backgound could be reintroduced at some point in the future. Sorry for noticing this sooner. Cheers.

Orthology Database

(Moved from Portal:Gene_Wiki/Discussion#Orthology_Database.)

I am an author of the German wikipedia and also edit sometimes in the English wikipedia, mainly on biochemistry articles. I have been active on some gene articles and I noticed that the GNF Protein box and the GNF Ortholog box templates have a lot of useful links to other databases but these mainly cover single genes or gene products (like Entrez, Ensembl and Uniprot) but a link to a phylogenetic database is not present. So I felt that there would be a lot of added value if there were a direct link to a phylogenetic database that lists orthologs of a specific gene. This would allow the exploration of its corresponding genes in hundreds of complete genomes. There are already links from Uniprot to phylogenetic databases but you have to scroll all the way down to find them.

I am currently working with a group at ETH that created the OMA-database (http://www.omabrowser.org). It is one of the biggest orthology databases and many other website such as Uniprot and Ensembl link to OMA. Since I know this project best I would suggest to integrate this website into the GNF Protein box but there are also other projects which might be more suited for Wikipedia. On the technical side, the change in the infobox would only consist of a small adjustment since the database could be called directly with the uniprot entry ID (e.g. http://www.omabrowser.com/cgi-bin/gateway.pl?f=DisplayEntry&p1=PROCA02187 in the case of OMA). Did you discuss such an idea already? What do you think? Greetings --hroest 12:07, 9 September 2009 (UTC)

Hi, the overlap here is quite large because this protein is only present in higher eukaryotes but another example might look different if there are also prokaryotes in the group. For other databases see e.g. http://www.uniprot.org/uniprot/P08908. If you scroll all the way down you find Phylogenomic databases, unfortunately the link to HoverGene does not seem to work. To compare Homologene and OMA use these two links. There are also other databases such as EggNog (entry would look like this) or RoundUp (which could not find the sample gene I have used here but another example looks like [10] this).
The group that published OMA also wrote a comparative paper. They claim to be the biggest orthology database with currently 830 species. Homologene on the other hand has only eukaryotic species, so basically they have 20 species. This might be another point to consider. In their paper the group names several good orthology databases which we might consider here [...]the ranking of the best performing projects (OMA, RoundUp, Homologene, Inparanoid). Again, Inparanoid is limited to eukaryotic species. Greetings --hroest 11:29, 10 September 2009 (UTC)

talk
) 18:01, 10 September 2009 (UTC)
Well I do not believe that differences in orthology assignments in prokaryotes are relevant for a lot of users but I believe that linking to a database that does NOT have prokaryotes gives a wrong impression to the average wp user. Sometimes it would be very interesting to see that a certain gene has orthologs in prokaryotes and the other thing is that if a database does not list any orthologs then an average user might assume that there aren't any and he or she might not be aware that in Homologene only eukaryotes are listed. I do not believe that genes of prokaryotes are less noteable (but this is my personal opinion) and it would be nice to have a box that could be used for all genes and not only eukaryotic ones. Second, this might be a good idea but there is already some information about orthology in mice in the box. But I agree that it would be nice to have more information and more links. It would also be helpful have a field like "conservation" which would contain values such as "Mammals only", "Primates only" or "whole tree of life" which would inform the user, where the gene he/she is looking at is present in the tree of life. But I believe that evolution is not that simple thus making this idea not very feasible. Third, this is a point to consider especially since WP users are often nonspecialists. But we should also consider the opinion of the scientific community and maybe have a compromise solution. Greetings --hroest 19:59, 12 September 2009 (UTC)

Lower eukaryotes

Hello all. When reading Wikipedia articles or articles found in PubMed I often come across the term 'lower eukaryotes'. In my opinion, it is a very confusing term and therefore I'd like to propose two possible things: translate 'lower eukaryotes' in Wikipedia articles to the organisms / tax intended, or create an article that explains what it is scientists mean when they (or we ;-)) refer to an organisms being a 'lower eukaryote'.

How do you feel about this subject and my suggested solutions? -- WKoets (talk) 13:26, 15 October 2009 (UTC)

I would write about it (possibly in a separate section) in the eukaryote article and then link the word to that section of the eukaryote article so if readers don't understand the term, they can quickly find out what it means. Tyrol5 [Talk] 20:33, 15 October 2009 (UTC)
You could mention it in that article, but as the term is quite meaningless in biology, I don't think it deserves a whole section.

This issue gets confounded, though, with the difference between Dutch and English in the number of references preferred in articles. Ucucha 21:16, 10 November 2009 (UTC)

Another bullet point in the Posttranscriptional regulation should do the trick. --Paul (talk) 22:53, 9 November 2009 (UTC)
That section says "These processes occur in eukaryotes but not in prokaryotes" - riboswitches are (with one current exception) the opposite.

I think that section is not terribly accurate or well written. I don't see how the things mentioned under translational regulation are not forms of posttranscriptional regulation.

Synthase vs synthetase

I've noticed (what I consider to be) some inconsistencies in Wikipedia regarding the utilization of synthase versus synthetase.

Is that right or outdated? Thanks, Pdcook (talk) 02:06, 16 November 2009 (UTC)

That is the correct distinction, with synthetases breaking a diphosphate bond in a nucleoside triphosphate. However, this is no longer the recommended nomenclature. The systematic names of all these enzymes are now ligases. For example, EC 6.3.1.2
glutamate-ammonia ligase. These are common names though and still in wide use. Tim Vickers (talk

I agree with PDCook -- it looks correct, but people are most likely getting confused with the twists, and colour coding the different strands may help.

Mass update of PDB images

Based on a discussion at GeneWiki, I've written a small program to do some automated polishing of PDB images first uploaded by ProteinBoxBot. A list of test case images is available at User:Emw/PDB Sandbox -- here, for comparison, original images uploaded by ProteinBoxBot are set alongside images produced by the new method. Before going on to apply these changes to the roughly 2800 PDB images contained in PBB templates, I'd like to gather feedback and suggestions from the WP:MCB community. Thanks in advance for any input. Emw (talk) 22:27, 24 November 2009 (UTC)

They are better in full size, but definitely more fuzzy (and therefore worse) when rescaled. --Cyclopiatalk 23:04, 24 November 2009 (UTC)
I don't quite understand. Are you saying that the protein structure images are fuzzier (less resolution?) when they're scaled down to fit in the template? Could you give an example? Emw (talk) 04:43, 25 November 2009 (UTC)
I don't know how to quantify, but it's not a resolution problem. Your new images are much better in general, but do not look nice when rescaled to fit in the template. To me the new ones look fuzzy, while the lo-res old ones seem definitely more crisp when rescaled in the template -I guess it's an aliasing problem, but I don't know how to solve it. --Cyclopiatalk 14:44, 25 November 2009 (UTC)
Left hand image is rather lower quality and taken from a lower resolution image. It includes JPEG compression artifacts. :-/ Any "sharpness" you might perceive is illusionary. Possibly due to those artifacts? --Kim Bruning (talk) 20:55, 25 November 2009 (UTC)
It is utterly irrelevant if it is illusionary -I mean, it is obvious that it is "illusionary" because the left images is of objectively much lower quality. But when rescaled, the higher quality image looks worse. That's all it matters, even if it is just an artefact. It is counterintuitive but it is not as strange as it may seem -it depends on the rescaling, aliasing effects, etc. A way should be found to make the new image look good even when rescaled. I checked on different LCD screens of different resolution and I still see the same effect. --Cyclopiatalk 21:29, 25 November 2009 (UTC)
I also tried now with both Firefox and Konqueror, to see if it's a browser-specific effect, but it seems not. --Cyclopiatalk 21:32, 25 November 2009 (UTC)
I wasn't able to pick out the more pronounced pixelation typical of aliasing issues in the down-sized new images. But I may just be insensitive to it. (FWIW, I've viewed it in several browsers on Windows Vista. Could this be an OS-specific issue?) To get a better idea of the situation I zoomed in on the old and new images in the templates using the Image Zoom extension for Firefox. With both images zoomed to 200%, the old image at left is noticeably more pixelated than the new image at right. Emw (talk) 22:06, 25 November 2009 (UTC)
I'm quite puzzeled by this. The right hand image has a higher resolution and *should* downsample more cleanly. If it's not an illusion, it might be interesting to ask a developer to take a more detailed look (perhaps a different downsampeling method is used for the two images? I can't imagine why though, unless it has to do with timing.)
At any rate, I think the higher resolution image should be retained (as well), even if the thumbnail appears more "fuzzy". --Kim Bruning (talk) 00:32, 26 November 2009 (UTC)

I am sorry of not having made myself clear. The effect I see is the opposite of pixelated. The correct word I wanted to say (I am not a native English speaker) is blurry. In my view the new image, when resized, looks subtly but noticeably blurry, noticeably enough that it is quite annoying for the eyes to look at it. I fully agree that the high resolution image should be retained, but I'd like to have a way to retain it or to process it so that the resized image looks better. --Cyclopiatalk 13:17, 26 November 2009 (UTC)

In order to produce crisp ray-traced images with a light background in PyMol, add the following to your script:
  • set cartoon_transparency = 0.0
  • set depth_cue = 0
  • set ray_trace_fog = 0
I think this will make the PyMol generated image look sharper even when reduced in size. In any case, fuzzy or not, I think the new png PyMol images (right hand side) look better at any size compared to the older jpg (left hand side) images. Cheers.

Thanks for the suggestion. I've added fogless versions of the new images for 1xu7, 1lui and 2a07. Which is preferable -- the foggy or fogless version? Emw (talk) 00:23, 27 November 2009 (UTC)
These are much better than the JPEGs, excellent work. In my system, both foggy and fogless look equally awesome at thumbnail size, but I believe "fogless" is preferable, as it does produce a crisper image and a smaller file size (that's how I always produce my PyMol images, anyway). Fvasconcellos (t·c) 00:31, 27 November 2009 (UTC)
To me they look practically identical. They both still look definitely blurry to me at thumbnail size. Again, they are for sure much better than the JPEGs, I don't dispute that, but it is disappointing that the thumbnail can't be crisp. However for some reason it seems it is just me, so let's be it. --Cyclopiatalk 00:54, 27 November 2009 (UTC)
I briefly discussed the blurriness problem with User:Brion last night at #mediawiki. He mentioned that some sharpening is applied to JPGs -- usually photographic images -- but wasn't sure what is done to PNGs. Perhaps that's the culprit, but as Cyclopedia notes others apparently aren't seeing any problematic blurriness (and it is independent of whether the image is foggy or fogless).
It seems there's consensus to move forward with the mass update using a fogless rendering. Are there any other feature requests? Emw (talk) 01:46, 27 November 2009 (UTC)
Come to think of it, I think the rendering of DNA in File:C-Myc-DNA_complex.png is better than the way it's shown in the test images (e.g. File:Protein_FOXP2_PDB_2a07.png). I've added a new test case for DNA rendering here -- any thoughts? Emw (talk) 17:39, 27 November 2009 (UTC)

Merge?

But I could be mistaken. --CopperKettle 07:17, 13 December 2009 (UTC)

  • I think they are the same and ought to be merged. This is probably a case of a geneticist creating an article for the gene and an enzymologist creating an article for the enzyme. I've seen this happen a number of times.PDCook (talk) 15:25, 13 December 2009 (UTC)
  • In this particular case, I think these two articles could be merged since there appears to be only one protein in the human genome that possesses this particular enzymatic activity (i.e., same EC number) . However there are other cases where several proteins in the same genome may have the same enzmatic activity in which case it would be useful to retain the enzyme page (in addition to the individual gene/protein specific pages) to represent the family of proteins.

Beautiful, well done. A step up from the current images from EBI for sure... Has anyone at wikicommons complained that the images are all uploaded to a single category?

Yes, someone made that very complaint at the PDBbot's BRFA at Commons. As I mentioned there, I think it would take less work to add a SCOP category for each image if source code by Donabel_SDSU were ported for use by PDBbot.
I was also thinking that it may be worthwhile to replace the static image in the Gene Wiki with a spinning animation of the protein structure, similar to the animated .gif in the lead of
Ogg Theora videos, which would allow the animations to be paused. Emw (talk

Yeah, I'm much less enthusiastic about the animations. A bunch of interested users prototyped a few ideas a while back (the discussion must be in the archives here somewhere). But I think the consensus then was that they were a) distracting, b) resource-intensive on the client's browser, and c) of lower visual quality than the static images. In retrospect, I strongly agree with the eventual decision to stay with the static images (and especially so now that we have your higher quality static images)... Cheers,

Thanks for the pointer to that discussion. In that thread there seemed to be some enthusiasm for an animation within a 'show/hide' template. There weren't any examples provided, so I made a rough prototype at User:Emw/PDB_Sandbox/Animation. There are a few elements that could likely use polishing (e.g., minimizing or doing away with the 'v d e' links). As it is, though, the animation seems easily ignorable and allows the client to decide whether to use a resource-intensive feature of the page. With regard to visual quality, I think higher-resolution videos (i.e., with ray-traced frames) would be possible. Emw (talk) 06:26, 12 February 2010 (UTC)
Thanks for experimenting with this. I think making the animation collapsible is a good idea.

If there are no objections, I'm going to redirect it, as the original page author keeps making poor edits and has removed maintenance templates.

Alex, so would clan be the highest level of organization that you'd want to link to (or are there others)? And in the case where the most natural link is to a clan, would you want to see that in addition to or instead of multiple links to PFAM entries? If in addition to, what's the largest number of PFAM entries per clan? Just trying to think of the possibilities here... Cheers,

Yes clan is the highest level we would want to link to. The link looks like this: http://pfam.sanger.ac.uk/clan/CL0001 I was thinking about using this instead of a link to a Pfam family. But I guess one could consider having a Pfamclan link in the box and link to both the family and the clan. Thats an interesting idea and would be simpler to implement than having two sorts of identifiers for a Pfam link in the family box. A small number of clans contain over 100 Pfam families, so I don't think we would want to link to every family in a clan from a wikipedia page. Alexbateman (talk) 10:06, 1 April 2010 (UTC)

That does look great. Thanks Boghog. I suspect the box usage should be determined by the scope of the article.

OK that looks good, thanks! I am getting bit confused with all the different boxes though. I don't think we need to proliferate and have another box {{

Yes, it's great. The box allows including any number of different databases (e.g. PANTHER or enzyme databases), some of which may or may not be used for each specific family.

growth media and a series of possibly stupid questions

I have found a set of pages which could do with a tidy up (except I am not a microbiologist and I just grown plasmids and protein), basically:

petri dishes with agar
.
However this is what I found odd:

Massive reorganization of biomolecular structure articles

I've been perusing the articles on nucleic acid and protein structure recently, and I think that this set of articles could be improved by some reorganization. The theory behind this is that protein structure is fairly different than nucleic acid structure, but DNA structure and RNA structure are very similar, and the article organization should reflect this. Currently, the coverage of many of the articles is skewed towards one type of biomolecule or structure even though the title indicates a broader topic. Since there are pretty major changes, I thought it would be a good idea to discuss them here first.

I suggest the following article moves:

Primary structure -> Protein primary structure

Secondary structure -> Protein secondary structure

Tertiary structure -> Protein tertiary structure

All three of these articles are almost entirely about protein structure. The short bits about nucleic acid structure can be easily moved elsewhere.

DNA structure -> Nucleic acid secondary structure

RNA tertiary structure -> Nucleic acid tertiary structure

As it turns out, the DNA structure article is almost entirely about secondary structure. A moderate amount of rewriting will be required to explain the differences between DNA and RNA structure. A

Nucleic acid primary structure
article should be written, either from scratch or by moving text from another article.

RNA structure -> Biomolecular structure

This article will serve as a summary-style introduction pointing to all the other pages. The current RNA structure article has the right organization to form the core of this article. "Primary structure", "secondary structure," and "tertiary structure" should all redirect here.

One random question—is there such a thing as nucleic acid

quaternary structure
? Such a term doesn't seem to be in general use, but I want to make sure I'm not just unaware of it.

I intend to resolve the double redirects when I do the moves. I did a quick search on Google Scholar, and it looks like "DNA quaternary structure" is used in relation to the higher-level organization of DNA in a chromosome (e.g.
doi:10.1002/bip.1977.360160308). I suppose this includes DNA-histone interactions as well. There might be enough material to make a short article; if anyone comes across any good references I'd much appreciate it. Antony-22 (talk

Nice work Antony-22! Regarding the Nucleic acid design, the Vienna suite of programs has a tool RNAinverse which has been fairly widely used for generating sequences consistent with a defined structure:

The Protein design article makes no mention of Ancestral sequence reconstruction but I believe it and the nucleic acid design should. Eg. there has been quite a bit of work on reconstructing ancient genomes:
ASR has also been proposed for vaccine design:

) 15:47, 11 April 2010 (UTC)
Regarding the reorganization of the biomolecular structure sections: Certainly this was needed, and overall, the approach taken is very good. Last year, when I set out to find a topic for my class to work on, it was clear the entries were a disorganized collection of good intentions. I would like to make a few suggestions:
1) I would not lump RNA and DNA higher order structure (tertiary) together. The RNA tertiary structure section is already missing a lot of text and figures that I removed from my classes' efforts as they did not pass our quality control. In short, this is a section that will grow in size. DNA higher order structure is different and more limited compared to RNA. Also, structures formed by DNA often serve different purposes. I think if you make a single Nucleic Acid Tertiary structure section, you will find in a year that you are trying to divide it in two (or more!). You might as well start now by having a separate DNA and RNA section. Alternatively, you can have a Nucleic Acid Structure section that is relatively brief and describes differences between RNA and DNA tertiary structures, but then points to an RNA Tertiary Structure page and a DNA Tertiary Structure page
2) Quaternary structure is a not a very modern idea. While it is a term worth knowing, the difference between quaternary structures and tertiary structures are simply the presence of a linker. For example, a coiled coil can be a quaternary structure formed from two alpha-helices. It is also a a tertiary structure in helix bundle proteins. The details of the structure interactions are identical. Function, and energy is affected, but not structure.
3) The biomolecular world is bigger than just protein and nucleic acids. I would make entries that anticipate polysaccharides, lipids and small molecules. Instead of quaternary structure, you might imagine making entries that represent recognition of one biomolecule by another. All the other fun structure entries represent interactions among these different molecule types. Helicases are an example of protein:DNA interactions, riboswitches are examples of RNA:small molecule interactions etc etc. Quaternary structure then just becomes the special case of self:self recognition. MirankerAD (talk) 08:36, 12 April 2010 (UTC)
Paul: thanks for the refs! I'm not very familiar with ancestral sequence reconstruction, but feel free to add the material wherever you think it is appropriate. I'll definitely use the Vienna reference in Nucleic acid design, which should be appearing very soon.
Narayanese: Sounds like a good plan. I'm a bit torn since "Nucleic acid sequence" is more common especially in a less technical setting, but "primary structure" is consistent with the nomenclature of the other articles. I think your plan would work well, though.
MirankerAD: I figure that RNA and DNA tertiary structure articles can be split out as you describe once there's actually material on both. I too am not entirely clear on the difference between tertiary and quaternary structure for nucleic acids; I don't think the latter term is used frequently or particularly consistently. I figure that the Nucleic acid quaternary structure article would be a shorter article describing the different ways in which the term is used, and linking to other articles that describe them. I also think it could be great if Biomolecular structure could be further expanded to talk about the higher-level structure of other biomolecules; unfortunately I don't really know enough about non-nucleic acid structure to do it myself.
Antony-22 (talk) 20:52, 13 April 2010 (UTC)
I'd like to extend my earlier thoughts. It strikes me that there isn't so much of a distinction between DNA and RNA structure, as there is between double-helical and "globular" nucleic acid structures: an RNA double helix will have similar properties as a DNA duplex, and globular DNA structures like DNAzymes are similar to globular RNA structures. The thing is, biologial DNA's are almost always double helical, while biological RNA's are almost always globular, so it's easy to conflate the two. I've been trying to introduce this distinction as I've been editing the articles, but the implications for the article organziation still needs further thought. Antony-22 (talk) 02:58, 14 April 2010 (UTC)

Biomolecular structure, phase II

I've been doing some more thinking. My reading indicates that nucleic acid secondary structure strictly consists of a list of the base pairs; the structure of the double helix itself strictly speaking is tertiary structure, though it's intimately related with secondary structure. A lot of the material in Nucleic acid secondary structure is about double helix structure though. So I'm thinking about the following changes:

The expansions in the primary and secondary structure articles will mostly be summary-style grabs from other articles. Please feel free to suggest additional articles to include, and let me know what you think of the changes in general.

It's also worth mentioning, Nucleic acid design is up and was DYK a few days ago. Antony-22 (talk) 05:38, 24 April 2010 (UTC)

The first is relevant graphic of a protein but way too detailed and therefore fuzzy at the displayed size. The second is a very clear but generic icon. Another issue is that the MCB portal encompasses both molecular and cellular aspects and it would be nearly impossible to capture both a small icon. Here is another suggestion, but unfortunately it is not much better:

A way to capture both molecular and cellular aspects in one image might be to use a depiction of the place of DNA in a cell nucleus, like this, which actually looks pretty decent at 40 px.

  1. The cloned copy has only pulled across the text and not the corresponding references, leaving the daughter page unreferenced.
  2. Content has been added to the main article, but not the daughter so that the latter is different to the former rather than a superset.
  3. There are sometimes minor inconsistencies between the two versions.

I propose to clean up some of these, but given my non-expert status, I wanted to alert project members and get feedback before doing so.

Rilonacept

Rilonacept is an engineered fusion protein. I'm wondering if it is also classified as a designed protein, i.e. one created by site-directed mutagenesis rather than directed evolution. Any idea? Lfh (talk) 20:26, 15 May 2010 (UTC)

This is a semantic question and hence there may be no universally agreed upon answer. The following is my interpretation. While Rilonacept in a broad sense is a designed protein, it was not designed from scratch nor was it made from calculated changes from a known structure. Rather it is a fusion protein composed of parts of two known proteins and combines properties of each of the two proteins into one molecule. Hence in the way that designed proteins are usually defined, Rilonacept is not a designed protein.

Boghog is right (and crystal clear, kudos). Parenthetically, it is also non-sythtetic (also a grey definition). I was wondering are all artificial proteins engineered protein? In vitro/directed evolution creates artificial/engineered proteins (I think at least), but do random shuffling experiments?
