Peptide YY (PYY) is secreted as a 36 amino acid, straight chain polypeptide, and is found in greatest concentrations in the terminal ileum, colon and rectum. After secretion, dipeptidyl peptidase IV (DPP-IV) cleaves the N-terminal Tyrosine-Proline residues from PYY(1-36), producing PYY(3-36). PYY(1-36) acts at all four human Y receptors, Y1, Y2, Y4 and Y5, while PYY(336) is a specific Y2 recept...
