Function
PLCE1_RAT 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. PLCE1 is a bifunctional enzyme which also regulates small GTPases of the Ras superfamily through its Ras guanine-exchange factor (RasGEF) activity. As an effector of heterotrimeric and small G-protein, it may play a role in cell survival, cell growth, actin organization and T-cell activation. In podocytes, is involved in the regulation of lamellipodia formation. Acts downtream of AVIL to allow ARP2/3 complex assembly (By similarity).[UniProtKB:Q9P212][1] [2] [3]
