What [Leu31, Pro34]Peptide YY, PYY, human is studied for
- Incretin (GLP-1 / GIP) receptor signaling
- Appetite and satiety-circuit research
- Gastric motility and emptying assays
- Gut–brain axis and vagal signaling models
Mechanism of action
[Leu31, Pro34]Peptide YY, PYY, human sits within the GI / Gut research class (CPC reference PEPY-002). Gut peptides engage GPCRs on enteroendocrine cells, vagal afferents, and central nuclei, modulating motility, secretion, satiety, and glucose-dependent insulin release. Investigators typically incorporate [Leu31, Pro34]Peptide YY, PYY, human as a reference standard, tool ligand, or substrate in the assay contexts listed above. cAMP HTRF, in vitro islet insulin secretion, and food-intake models in rodents.
Frequently asked questions
