β-Melanocyte Stimulating Hormone (MSH), human TFA, a 22-residue peptide, acts as an endogenous melanocortin-4 receptor ( MC4-R ) agonist [1].
In Vitro, β-Melanocyte Stimulating Hormone (MSH), human (β-MSH) has high affinity at both human MC4-R transfected into CHO cells (Ki=11.4±0.4 nM) and MC4-R in rat hypothalamic homogenates (Ki=5.0±0.4 nM)[1].
