Housekeeping gene

Source: Wikipedia, the free encyclopedia.

In

constitutive genes that are required for the maintenance of basic cellular function, and are expressed in all cells of an organism under normal and patho-physiological conditions.[1][2][3][4] Although some housekeeping genes are expressed at relatively constant rates in most non-pathological situations, the expression of other housekeeping genes may vary depending on experimental conditions.[1][5]

The origin of the term "housekeeping gene" remains obscure. Literature from 1976 used the term to describe specifically

RT-PCR. Recently a web-based database of human and mouse housekeeping genes and reference genes/transcripts, named Housekeeping and Reference Transcript Atlas (HRT Atlas), was developed to offer updated list of housekeeping genes and reliable candidate reference genes/transcripts for RT-qPCR data normalization.[1] This database can be accessed at http://www.housekeeping.unicamp.br

Housekeeping gene regulation

Housekeeping genes account for majority of the active genes in the genome, and their expression is obviously vital to survival. The housekeeping gene expression levels are fine-tuned to meet the metabolic requirements in various tissues. Biochemical studies on transcription initiation of the housekeeping gene promoters have been difficult, partly due to the less-characterized promoter motifs and transcription initiation process.

Human housekeeping gene promoters are generally depleted of TATA-box, have high GC content and high incidence of CpG Islands.[7] In Drosophila, where promoter specific CpG Islands are absent, housekeeping gene promoters contain DNA elements like DRE, E-box or DPE.[8] Transcription start sites of housekeeping genes can span over a region of around 100 bp whereas transcription start sites of developmentally regulated genes are usually focused in a narrow region.[9][10][11] Little is known about how the dispersed transcription initiation of housekeeping gene is established. There are transcription factors that are specifically enriched on and regulate housekeeping gene promoters.[12][13] Furthermore, housekeeping promoters are regulated by housekeeping enhancers but not developmentally regulated enhancers.[14]

Common housekeeping genes in humans

The following is a partial list of "housekeeping genes." For a more complete and updated list, see HRT Atlas database compiled by Bidossessi W. Hounkpe et al.[1] The database was constructed by mining more than 12000 human and mouse RNA-seq datasets.[1]
