Glucagon is a member of a multigene family comprising of Secretin, Vasoactive Intestinal Peptide (VIP), Gastric Inhibitory Peptide (GIP) and others like Glicentin and Oxyntomodulin (OXM), which differs from glucagon by C-terminal octapeptide. The glucagon precursor contains at least 3 intervening sequences that divide the protein-coding portion into 4 regions corresponding to the signal peptide and part of the N-terminal peptide, the remainder of the N-terminal peptide and glucagon, glucagon-like peptide-1 (GLP1), and GLP2. SECR, Secretin is a 27-amino acid hormone (chr 11p15) produced by specific endocrine cells, S cells, located in the mucosa of the proximal small intestine. It has been known to be a potent stimulus for the secretion of bicarbonate-rich pancreatic juice. Secretion of secretin is stimulated by the presence of either acidic pH or fatty acids in the duodenum. Secretin stimulates ductal bile secretion by directly interacting with cholangiocytes, promotes osmotic water movement in cholangiocytes by inducing the exocytic insertion of AQP1 into plasma membranes.
