We characterized the molecular complex of the melatonin MT(1) receptor, which couples to G(i) proteins and the regulator of G-protein signalling (RGS) 20. We proposed a model wherein one G(i) and one RGS20 protein bind to separate protomers of MT(1) dimers in a pre-associated complex that rearranges upon agonist activation. Our data extend the concept of asymmetry within GPCR dimers, reinforce the notion of receptor specificity for RGS proteins and highlight the advantage of GPCRs organized as dimers in which each protomer fulfils its specific task by binding to different GPCR-interacting proteins.
