Melanocyte-stimulating hormone (MSH) stimulates pigmentation in mammals by activating specific cell surface MSH receptors (MC1-Rs) on melanocytes. MC1-Rs on normal human melanocytes have been difficult to detect and characterise. The pharmacological characterisation of a cloned human MC1-R (hMC1-R) is reported here, and directly compared with that of a cloned mouse MC1-R (mMC1-R). The human and mouse MC1-Rs are equally sensitive (EC50= 1–2pM) to the super potent analogue of α-MSH, NDP-MSH. In contrast with the mMCl-R, the hMCl-R is also very sensitive to α-MSH (EC50= 2pM), ACTH (EC50= 8pM), and Lysγ3-MSH (EC50< 10−10M). This suggests that in man, in contrast with rodents, both ACTH and Lysγ3-MSH may have physiological roles in pigmentation.
