Previous GeneCards Identifiers for DGKE Gene
Diacylglycerol kinases are thought to be involved mainly in the regeneration of phosphatidylinositol (PI) from diacylglycerol in the PI-cycle during cell signal transduction. When expressed in mammalian cells, DGK-epsilon shows specificity for arachidonyl-containing diacylglycerol. DGK-epsilon is expressed predominantly in testis. [provided by RefSeq, Jul 2008]
GeneCards Summary for DGKE Gene
DGKE (Diacylglycerol Kinase Epsilon) is a Protein Coding gene. Diseases associated with DGKE include Nephrotic Syndrome, Type 7 and Hemolytic-Uremic Syndrome. Among its related pathways are Signaling by GPCR and Effects of PIP2 hydrolysis. Gene Ontology (GO) annotations related to this gene include NAD+ kinase activity and diacylglycerol kinase activity. An important paralog of this gene is DGKD.
UniProtKB/Swiss-Prot Summary for DGKE Gene
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).
Diacylglycerol kinases (DGKs) are a group of ten enzymes that metabolize 1,2,diacylglycerol (DAG) to produce phosphatidic acid (PA). They all contain a conserved C'-terminal catalytic domain and two cysteine-rich Zn2+-finger motifs with varied regulatory domains.
