WebWe would like to show you a description here but the site won’t allow us. WebDiacylglycerol kinase alpha. DGK alpha is an enzyme that catalyzes the conversion of diacylglycerol to phosphatidic acid, thus regulating the level of these substances in the cell [4]. Diacylglycerol kinase alpha acts as a central switch between signaling pathways activated by secondary messengers such as DAG and phosphatidic acid [4].
WebDiacylglycerol kinases (DGKs) are a family of enzymes that catalyze the ATP-dependent phosphorylation of diacylglycerol (DAG) to phosphatidic acid (PtdOH). Despite the critical role in lipid biosynthesis, both DAG and PtdOH have been shown as bioactive lipids mediating a number of signaling pathways. WebDiacylglycerol and phosphatidic acid are two lipids that act as second messengers in signaling cascades. Their cellular concentrations are regulated by the encoded protein, and so it is thought to play an important role in cellular signal transduction. Alternative splicing results in two transcript variants encoding different isoforms.

WebFeb 6, 2024 · DAG can emanate from stored fat as triacylglycerol, as well as the glycerophospholipid phosphatidylinositol (PI). In order to produce DAG from triacylglycerol, one of the outer acyl-CoA groups is deacylated by a lipase. Conversely, DAG synthesis from PI requires removal of the inositol group. how are earls addressedWebSaline and osmotic stresses stimulate PLD/diacylglycerol kinase activities and increase the level of phosphatidic acid and proline in barley roots Author links open overlay panel Maria V.
