Phosphatidylinositol 4-phosphate 5-kinase type-1 gamma (Pip5k1c)

PtdIns(4,5)P2 is involved in many different cellular processes and is the substrate to form phosphatidylinositol 3,4,5-trisphosphate (PtdIns(3,4,5)P3), another second messenger. Nearly all PtdIns(4,5)P2 is considered to occur via type I phosphatidylinositol 4-phosphate 5-kinases given the abundance of PtdIns4P.

Participates in many different cellular processes like vesicle mediated transport, cell adhesion, cell polarization and cell migration. Together with PIP5K1A is required for phagocytosis, but they govern different types of actin remodeling in sequential steps.
