Description : Glucagon(NH2-His-Ser-Gln-Gly-Thr-Phe-Thr-Ser-Asp-Tyr-Ser-Lys-Tyr-Leu-Asp-Ser-Arg-Arg-Ala-Gln-Asp-Phe-Val-Gln-Trp-Leu-Met-Asn-Thr-COOH) is a peptide hormone, secreted by the pancreas, that raises blood glucose levels. Glucagon’s effect is opposite that of insulin, which lowers blood glucose levels. Miniglucagon (Glucagon 19–29) is a potent and efficient inhibitor of secretagogue-induced insulin release through a Ca2+ Pathway*. Miniglucagon is a novel local regulator of the pancreatic islet physiology. Any abnormal inhibitory tone exerted by this peptide on the β-cell results in impaired insulin secretion, as observed in type 2 diabetes. Miniglucagon is a component of the positive inotropic effect of glucagon. Some evidence has shown that glucagon processing into miniglucagon may be essential for the positive inotropic effect of glucagon on heart contraction.
