Protein: 1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase epsilon-1 (EC 3.1.4.11) (Phosphoinositide phospholipase C-epsilon-1) (Phospholipase C-epsilon-1) (PLC-epsilon-1) (Q99P84)
Organism: Rattus norvegicus (Rat)
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. 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 downstream of AVIL to allow ARP2/3 complex assembly (By similarity).
Subcellular location: Cytoplasm, cytosol {ECO:0000250|UniProtKB:Q9P212}. Cell membrane {ECO:0000250|UniProtKB:Q9P212}. Golgi apparatus membrane {ECO:0000250|UniProtKB:Q9P212}. Cell projection, lamellipodium {ECO:0000250|UniProtKB:Q9P212}. Note=Recruited to plasma membrane by activated HRAS and RAP2. Recruited to perinuclear membrane by activated RAP1A. Isoform 1 and isoform 2 associates with Golgi membranes. {ECO:0000250|UniProtKB:Q9P212}.
