Secondary Information

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).

Additional Comments To date, four PLCδ isozymes have been reported. It has been suggested that PLCδ1 is involved in Alzheimer’s disease and is essential for hypertension.
