General description

Exendin-4 is an incretin mimetic 39-amino-acid peptide found in venom from the Gila monster (Helicoderma suspectum). Exendin-4 belongs to the glucagon-secretin family of peptide hormones and neuropeptides. It acts as a potent agonist of the GLP-1 receptor and is an insulinotropic agent (promotes insulin secretion) with a long half-life.

Exendin-4 mimics the activity of mammalian incretin hormone glucagon-like peptide 1 (GLP-1) and thus play a role in the control of glucose. This includes the secretion of insulin in a glucose-dependent manner, negative regulation of high glucagon secretion, and increased duration of stomach emptying. In type 2 diabetes patients, this peptide can be administered subcutaneously for glycemic control, when metformin is unable to produce adequate results. Exendin-4 promotes the neogeneration and proliferation of β-cells, and thus aids in the regeneration of pancreas. It acts as a ligand to exendin receptor and leads to an elevation of acinar cell cAMP levels.

Anti-Exendin-4 antibody specifically recognizes synthetic Exendin-4 and does not cross react with GLP-1.
