1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase epsilon-1 (PLCE1)

The creation of this 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 that also modulates small GTPases of the Ras superfamily through its Ras guanine- exchange factor (RasGEF) activity.

As an effector of both heterotrimeric and small G-protein, it may play a role in cell survival, cell growth, actin organization and T-cell activation. .
