Reaction: Hydrolysis of PIP2 by PLCG
- in pathway: FCERI mediated Ca+2 mobilization
Phosphoinositol 4,5-bisphosphate (PIP2) is cleaved in to two most important second messengers diacylglycerol (DAG) and Inositol 1,4,5-triphosphate (IP3) by phospholipase C (PLC). DAG remains within the membrane and activates protein kinase C (PKC) while IP3 leaves the cell membrane and binds to IP3 receptor that releases Ca2+ from endoplasmic reticulum (ER).
