Selective activation of 5-HTR promotes neural stem cell regeneration activity. As a 5-HTR selective agonist, 2-(5 chloro-2-methyl-1H-indol-3-yl)-N, N-dimethylethanolamine (ST1936) has been widely used to investigate the functions of the 5-HTR. The molecular mechanism of how ST1936 is recognized by 5-HTR and how it effectively couples with Gs remain unclear. Here, we reconstituted the ST1936-5-HTR-Gs complex in vitro and solved its cryo-electron microscopy structure at 3.1 Å resolution. Further structural analysis and mutational studies facilitated us to identify the residues of the Y310 and "toggle switch" W281 of the 5-HTR contributed to the higher efficacy of ST1936 compared with 5-HT. By uncovering the structural foundation of how 5-HTR specifically recognizes agonists and elucidating the molecular process of G protein activation, our discoveries offer valuable insights and pave the way for the development of promising 5-HTR agonists. | ||||||
