This is a receptor for GIP. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase. May form homodimers and heterodimers with GLP1R. Widely distributed including pancreatic islets, brain and various peripheral tissues. N-glycosylation is required for cell surface expression and lengthens receptor half-life by preventing degradation in the ER. Belongs to the G-protein coupled receptor 2 family.
