* Information From OMIM

Description: Glucagon is a 29-amino acid pancreatic hormone that counteracts the glucose-lowering action of insulin by stimulating glycogenolysis and gluconeogenesis. Human, rabbit, rat, pig, and cow glucagons are identical. Glucagon is a member of a multigene family that includes secretin (OMIM:182099), vasoactive intestinal peptide (VIP; OMIM:192320), gastric inhibitory peptide (GIP; OMIM:137240), glicentin, and others.
