CC -!- FUNCTION: The production of the second messenger molecules
CC diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) is mediated
CC by activated phosphatidylinositol-specific phospholipase C enzymes.
CC {ECO:0000256|PIRNR:PIRNR000956}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol) + H2O =
CC 1D-myo-inositol 1-phosphate + a 1,2-diacyl-sn-glycerol + H(+);
