Protein Function | PLC delta 4 is expressed in nucleus in response to mitogenic stimulation and plays important roles in cell growth as one of the early genes expressed during the transition from G1- to S-phase in the cell cycle.PLC delta 4 mRNA is expressed more remarkably in regenerating liver than in normal resting liver.Acrosome reaction in sperm. |

Biochemical Properties | Hydrolyzes the phosphatidylinositol 4,5-bisphosphate (PIP2) to generate 2 second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3). DAG mediates the activation of protein kinase C (PKC), while IP3 releases Ca2+ from intracellular stores.PLC isozymes contain catalytic X and Y domains as well as various regulatory domains, including the C2 domain,EF-Hand domain and pleckstrin homology domain(PH). |
