Gastric Inhibitory Peptide (human) (trifluoroacetate salt)

Gastric inhibitory peptide (GIP) is an endogenous 42-amino acid peptide incretin hormone that induces insulin secretion in response to glucose. It belongs to the secretin/glucagon superfamily of peptides, which includes secretin (Cay-24990, Cay-24561), glucagon (Cay-24204), glucagon-like peptide-1 (GLP-1, Cay-24460), GLP-2 (Cay-24414), and pituitary adenylate cyclase-activating polypeptide (PACAP, Cay-24769, Cay-24770). GIP is a GIP receptor agonist that binds to rat recombinant GIP receptors expressed in CHO-K1 cells (IC50 = 3.2 nM) and increases cAMP accumulation (EC50 = 377 pM). It stimulates insulin secretion from BRIN-BD11 rat pancreatic beta-cells when used at a concentration of 10 nM. GIP (1 pmol/min per 100 g) decreases blood glucose level and increases plasma insulin level in rats following glucose challenge. It also decreases plasma glucose level and increases insulin level in ob/ob mice following glucose challenge when administered at a dose of 25 nmol/kg.Formal Name: L-tyrosyl-L-alanyl-L-alpha-glutamylglycyl-L-threonyl-L-phenylalanyl-L-isoleucyl-L-seryl-L-alpha-aspartyl-L-tyrosyl-L-seryl-L-isoleucyl-L-alanyl-L-methionyl-L-alpha-aspartyl-L-lysyl-L-isoleucyl-L-histidyl-L-glutaminyl-L-glutaminyl-L-alpha-aspartyl-L-phenylalanyl-L-valyl-L-asparaginyl-L-tryptophyl-L-leucyl-L-leucyl-L-alanyl-L-glutaminyl-L-lysylglycyl-L-lysyl-L-lysyl-L-asparaginyl-L-alpha-aspartyl-L-tryptophyl-L-lysyl-L-histidyl-L-asparaginyl-L-isoleucyl-L-threonyl-L-glutamine, trifluoroacetate salt.
