C₂₅₈H₄₀₁N₇₉O₇₈ · 5857.4 Da

Kisspeptin-54 (KP-54), also known as Metastin, is the full-length C-terminally amidated peptide derived from the KISS1 precursor protein and the endogenous ligand for the KISS1R (GPR54) receptor. It is studied as a research tool for hypothalamic-pituitary-gonadal axis modulation, gonadotropin secretion dynamics, and tumor-metastasis suppression signaling.
