More Infomation

Target

Full Name
diacylglycerol kinase, epsilon 64kDa
Function
Membrane-bound diacylglycerol kinase that converts diacylglycerol/DAG into phosphatidic acid/phosphatidate/PA and regulates the respective levels of these two bioactive lipids (PubMed:15544348, PubMed:19744926, PubMed:22108654, PubMed:21477596, PubMed:23949095).

Thereby, acts as a central switch between the signaling pathways activated by these second messengers with different cellular targets and opposite effects in numerous biological processes (PubMed:8626589, PubMed:15544348).

Also plays an important role in the biosynthesis of complex lipids (PubMed:8626589).

Displays specificity for diacylglycerol substrates with an arachidonoyl acyl chain at the sn-2 position, with the highest activity toward 1-octadecanoyl-2-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycerol the main diacylglycerol intermediate within the phosphatidylinositol turnover cycle (PubMed:19744926, PubMed:22108654, PubMed:23274426).

Can also phosphorylate diacylglycerol substrates with a linoleoyl acyl chain at the sn-2 position but much less efficiently (PubMed:22108654).

Involvement in disease
Nephrotic syndrome 7 (NPHS7):
A form of nephrotic syndrome, a renal disease clinically characterized by severe proteinuria, resulting in complications such as hypoalbuminemia, hyperlipidemia and edema. NPHS7 is an autosomal recessive form characterized by onset of proteinuria usually in the first decade of life. The disorder is progressive, and some patients develop end-stage renal disease within several years. Renal biopsy typically shows membranoproliferative glomerulonephritis.
Hemolytic uremic syndrome atypical 7 (AHUS7):
An atypical form of hemolytic uremic syndrome characterized by acute onset in the first year of life of microangiopathic hemolytic anemia, thrombocytopenia, and renal failure. After the acute episode, most patients develop chronic renal insufficiency. Unlike other genetic forms of aHUS, AHUS7 is not related to abnormal activation of the complement system.
