Recombinant Human GIP protein (His tag)

Product Specifications

Background

Gastric inhibitory polypeptide (GIP), also known as the glucose-dependent insulinotropic peptide is a member of the secretin family of hormones. GIP, together with glucagon-like peptide-1 (GLP-1), belongs to the group of metabolic hormones called incretins that stimulate a decrease in blood glucose levels. GIP is derived from a 153-amino acid pro-protein encoded by the GIP gene and circulates as a biologically active 42-amino acid peptide. Engagement of Gastric inhibitory polypeptide receptors (GIPR) by GIP on pancreatic beta cells activates adenylate cyclase to regulate insulin compensation in the presence of high circulating glucose.
