Melanocortin receptor ligand, laboratory term

Melanocortin receptors (MC1R through MC5R) are G protein-coupled receptors for peptides processed from pro-opiomelanocortin, including alpha-MSH and ACTH. A melanocortin ligand is a sequence studied at one or more of those receptors. The class note is melanocortin ligands. The cellular category hub files these SKUs beside matrix peptides. Shared navigation is not shared identity.

Live, distinct URLs are Melanotan I, Melanotan II, PT-141, and KPV. KPV is the Lys-Pro-Val tripeptide from the C-terminus of alpha-MSH, not a full-length melanocortin analogue. None of these pages is a tanning product or a personal-use note.
