Anti-Pancreatic Polypeptide

Pancreatic polypeptide (UniProt: P01298; also known as PP, Obinepitide, Pancreatic prohormone) is encoded by the PPY (also known as PNP) gene (Gene ID: 5539) in human. Pancreatic polypeptide is a member of the neuropeptide Y family and is secreted protein that is produced by PP cells in the pancreatic islets of Langerhans. It is synthesized with a signal peptide (aa 1-29), which is subsequently cleaved off. It acts as a regulator of pancreatic and gastrointestinal functions. Two isoforms of pancreatic polypeptide have been described that are generated by alternative splicing. Pancreatic polypeptide release is functionally associated with increased satiety, delayed gastric emptying, inhibition of gallbladder motility, and regulation of energy expenditure. Its deficiency is observed in cases of pancreatic resection and chronic pancreatitis and is associated with significant reduction in PP cell mass and abnormally high hepatic glucose production even in the presence of endogenous insulin. (Ref.: Maxwell, J et al. (2014). Pancreas 43(4); 651-656).

~11 and ~20 kDa observed for isoforms 1 and 2; 10.45 and 18.79 kDa calculated for isoforms 1 and 2. Uncharacterized bands may be observed in some lysate(s).
