PHIP is a bromodomain-containing protein that binds the pleckstrin homology (PH) domain of insulin receptor substrate-1 (IRS1 ), modulates insulin signaling, and plays a role in pancreatic beta cell growth and survival. It stimulates cell proliferation through regulation of cyclin transcription and has an anti-apoptotic activity through AKT1 phosphorylation and activation.
