GtoPdb Ligand ID: 8970

Comment: GIP(3-42)NH2 is a truncated form of gastric inhibitory polypeptide (GIP) formed through degradation by dipeptidyl peptidase IV (DPP IV). At high concentration GIP(3-42)NH2 acts as a low potency antagonist of the GIP receptor, weakly antagonizing cAMP accumulation and insulin output in vitro, but no physiological antagonism is observed in vivo [1].
