A 22-amino acid polypeptide occurring in duodenal mucosa as a controller of normal gastrointestinal motor activity; in minute (ng) doses it induces powerful motor activity increases in the fundic gland area and antral pouches of the stomach, with an increase in pepsin output from the former. [motility + -in]

mo·til·in (mo-tilґin) a polypeptide hormone (2698 daltons, 22 amino acids) secreted by the enterochromaffin cells of the intestine; it increases motility of several portions of the gastrointestinal tract and stimulates pepsin secretion. Its release is stimulated by the presence of acid or fat in the duodenum; its physiologic role in gastrointestinal function is not yet known.
