General annotation (Comments)

Function	The production of the second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) is mediated by activated phosphatidylinositol-specific phospholipase C enzymes.
Catalytic activity	1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate + H2O = 1D-myo-inositol 1,4,5-trisphosphate + diacylglycerol.
Developmental stage	Expressed at all stages; increase in expression in the culminating fruiting body and during starvation.
Sequence similarities	Contains 1 C2 domain. Contains 1 EF-hand domain. Contains 1 PI-PLC X-box domain. Contains 1 PI-PLC Y-box domain.
Caution	It is uncertain whether Met-1 is the initiator.
