General description

Human peptide YY (PYY) is secreted by mucosal L cells in the distal ileum, colon and rectum. It consists of 36 amino acids. The gene encoding PYY is localized on human chromosome 17q21.1.

Application

Peptide YY human has been used as a supplement in Roswell Park Memorial Institute medium (RPMI medium) to culture pancreatic duct-derived cells.

Biochem/physiol Actions

Gut hormone that inhibits both secretin and cholecystokinin-stimulated pancreatic secretion. Endogenous nonselective agonist at NPY receptors.

Human peptide YY (PYY) has a role in food ingestion, gut motility and insulin secretion. The protein suppresses appetite. It has been associated with obesity and type 2 diabetes. PYY also has a role in energy homeostasis.
