WebPLCs are a group of enzymes that produce a diacylglycerol (DAG) and a phosphorylated molecule, such as phosphorylcholine (P-choline) and phosphorylethanolamine (P-ethanolamine) ( 4 ). It is conceivable that PC-PLC activity is important in maintaining steady-state levels of PC, thus influencing cell membrane integrity and function. WebDiacylglycerol (which remains embedded in the membrane) and 1,4,5-triphosphate (which is released into the cytosol) initiate further signal transduction pathways through the activation of protein kinase C and intracellular Ca 2+ release (Fig. 5).
