The gut hormone peptide YY (3-36) is a 36-amino acid peptide secreted from L-cells in the intestinal mucosa of the ileum and large intestine in proportion to caloric intake.

Labeling Target | Neuropeptide Y Receptor |
Application | PYY (3-36) plays an important role in the regulation of appetite control. It is assumed that this effect is mediated through Y2 receptors in the hypothalamic arcuate nucleus (ARC), a brain area responsible for the regulation of food intake. PYY (3-36) may represent a promising tool for the treatment of obesity. |

References | The gut hormone peptide YY (PYY) belongs to the pancreatic polypeptide (PP) family along with PP and neuropeptide Y (NPY). These peptides mediate their effects through the NPY receptors of which there are several subtypes (Y1, Y2, Y4, and Y5). The L cells of the gastrointestinal tract are the major source of PYY, which exists in two endogenous forms: PYY(1-36) and PYY(3-36). The latter is produced by the action of the enzyme dipeptidyl peptidase-IV (DPP-IV). PYY(1-36) binds to and activates at least three Y receptor subtypes (Y1, Y2, and Y5), whereas PYY(3-36) is more selective for Y2 receptor (Y2R). The hypothalamic arcuate nucleus, a key brain area regulating appetite, has access to nutrients and hormones within the peripheral circulation. Batterham, R. L., & Bloom, S. R. (2003).
