Protein Information (annotations from UniProt)

Database IDHIV0006362
UniProt IDP16885
Primary gene name(s)PLCG2
Synonym gene name(s)unknown
Protein name1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase gamma-2
Protein functionThe production of the second messenger molecules diacylglycerol, DAG and inositol 1,4,5-trisphosphate, IP3 is mediated by activated phosphatidylinositol-specific phospholipase C enzymes. It is a crucial enzyme in transmembrane signaling.
