Amylin is also known as islet amyloid precursor peptide (IAPP) and is co-secreted with insulin from pancreatic ß-cells. Amylin is an endogenous peptide hormone that exhibits gastrointestinal motility modulating activity, decreasing gastric emptying and suppressing gastric acid secretion; these actions slow food intake, preventing blood glucose spikes after eating and decreasing insulin demand. Misguided IAPP processing plays a significant role in the development of diabetes mellitus type 2. Like calcitonin, IAPP inhibits osteoclast activity and Ca2+ reabsorption in bones. This peptide binds to calcitonin-RAMP complexes.
