PPY

Official Full Name
pancreatic polypeptide -
Overview
Human Pancreatic Polypeptide (PP or Pancreatic hormone) is synthesized by neuroendocrine cells in the pancreas and is found in enteric nerves. Its release is stimulated during all phases of digestion and increases gastric acid secretion and motility in the stomach and intestine. PP has been shown to suppress appetite. Mice and men with overweight have relatively low levels of PP in contrast to anorexics, which have increased levels of PP. Transgenic mice with an over expression of PP showed reduced food intake, which was reversed by administration of PP antiserum. PP consists of 36 amino acids and has a molecular weight of 4391 Da. -

Protein Function
PPY has several biochemical functions, for example, G-protein coupled receptor binding,hormone activity,neuropeptide hormone activity. Some of the functions are cooperated with other proteins, some of the functions could acted by PPY itself.
