IUBMB Comments
This enzyme catalyses the Mg2+-dependent dephosphorylation of a 1,2-diacylglycerol-3-phosphate, yielding a 1,2-diacyl-sn-glycerol (DAG), the substrate for de novo lipid synthesis via the Kennedy pathway and for the synthesis of triacylglycerol. In lipid signalling, the enzyme generates a pool of DAG to be used for protein kinase C activation. The mammalian enzymes are known as lipins.
