Is motilin a hormone
Webb25 juni 1999 · Motilin is a 22–amino acid peptide hormone expressed throughout the gastrointestinal (GI) tract of humans and other species. It affects gastric motility by stimulating interdigestive antrum and duodenal contractions. A heterotrimeric guanosine triphosphate–binding protein (G protein)–coupled receptor for motilin was isolated ... WebbThe hormones may have indirect effects (neurally mediated) or direct actions (muscular) via smooth muscle motor activity. The GI hormones that primarily stimulate motor activity are gastrin, CCK, and motilin, while the peptides that inhibit motor activity are secretin, VIP, glucagon, and enteroglucagon.
