PHIP Products

PH-interacting protein (PHIP) was isolated as factor that binds to the pleckstrin homology (PH) domain of insulin receptor substrate-1 (IRS-1). PHIP was determined not to be a substrate of the insulin receptor but may instead serve to link IRS-1 to the insulin receptor. PHIP has also been implicated as a positive regulator of beta-cell mitogenesis and survival. PHIP is also known as WD-repeat-containing protein 11, WDR11, and IRS-1 PH domain-binding protein.
