Jagged1 (JAG1) is one of five cell surface proteins (
autosomal dominant disorder Alagille syndrome (ALGS) resulting from loss of function mutations within the gene. JAG1 has also been designated as CD339 (cluster of differentiation
339).
Structure and function
JAG1 was first identified as a
exons.[7]
The JAG1 protein encoded by JAG1 is the human homolog of the
intracellular domain being trafficked into the nucleus of the cell leading to the activation of different target genes.[8][9][10][11]
Expression profile and mouse studies
otocyst.[12] Generally, JAG1 expression patterns correlate with organ systems affected in ALGS, although it is important to note that not all tissues where JAG1 is expressed are affected in ALGS. More recently JAG1 expression has been found to be altered in breast cancer and adrenocortical carcinoma patients.[13][14]
Mouse models where the Jag1 gene is turned off in certain tissues (conditional knockout mouse models) have been used to study the role of Jag1 in many tissue specific areas. While
haploinsufficient for both Jag1 and Notch2 present with the ALGS phenotype.[15] Conditional gene knockout mouse models with Jag1 mutations targeted to the portal vein mesenchyme, endothelium, and cranial neural crest all exhibit features classic to those in individuals with ALGS, highlighting the role of this tissue type in disease origins[16][17][18][19][20]
Disease phenotype
ALGS is an
pulmonary stenosis that do not show the other clinical signs of the syndrome.[26]
Given the variable expressivity of the disease, there may be other genetic or environmental modifiers present beyond the original JAG1 mutation.
More recently, JAG1 expression changes have been implicated in many types of cancer. Specifically, up regulation of JAG1 has been correlated with both poor overall breast cancer survival rates and an enhancement of tumor proliferation in adrenocortical carcinoma patients.[13][27][28][29]
