SYSTEMATIC NAME
IUBMB Comments
ATP:1,2-diacyl-sn-glycerol 3-phosphotransferase
Involved in synthesis of membrane phospholipids and the neutral lipid triacylglycerol. Activity is stimulated by certain phospholipids [4,7]. In plants and animals the product 1,2-diacyl-sn-glycerol 3-phosphate is an important second messenger. cf. EC 2.7.1.174, diacylglycerol kinase (CTP).

uncompetitive inhibition of isoforms diacylglycerol kinase alpha and zeta, no inhibition of isoform epsilon. Binds to a site on the alpha and zeta isoforms that is exposed as a consequence of the substrate binding to the active site, the chiral specificity of the isoforms thus mimicks the substrate specificity

exposure of L6 cell myotubes overexpressing human insulin receptors to 25 mM glucose for 5 min decreases the intracellular levels of diacylglycerol, paralleled by transient activation of diacylglycerol kinase and of insulin receptor signaling. Following 30-min exposure, both diacylglycerol levels and diacylglycerol kinase activity return close to basal levels.
