Five receptors, four endogenous ligands, three reference synthetic analogs (MT-II, PT-141, afamelanotide) and two regulatory approvals (Scenesse, Vyleesi) cover a spectrum ranging from pigmentation to sexual function, via energy homeostasis and sebaceous exocytosis
A plausible binding pose of DHIQ docked into the apo D2.1 variant also shows that positively charged Lys64 selectively interacts with DHIQ (3.4 in distance), whereas protonated S -THIQ and R -THIQ are not favored (Supplementary Fig
