ILKAP/PP2C delta: Products

Integrin Linked Kinase 1 Associated Phosphatase (ILKAP), also called PP2C delta, is a serine/threonine phosphatase that is stimulated by manganese but inhibited by magnesium ions and is insensitive to the phosphatase inhibitor okadaic acid. ILKAP binds to ILK1 and dephosphorylates it, decreasing the stimulation of the GSK-3 beta pathway by cell adhesion without affecting Akt signaling. Transfection studies have shown that ILKAP activity inhibits cell cycle progression from the G1 to S phase. ILKAP is expressed in many tissues but is highest in liver, and skeletal and cardiac muscle. Its gene is found in a region of chromosome 2 that is frequently deleted in oral cancers.
