Authors: Makaía M Papasergi-Scott / Guillermo Pérez-Hernández / Hossein Batebi / Yang Gao / Gözde Eskici / Alpay B Seven / Ouliana Panova / Daniel Hilger / Marina Casiraghi / Feng He / Luis Maul ...Authors: Makaía M Papasergi-Scott / Guillermo Pérez-Hernández / Hossein Batebi / Yang Gao / Gözde Eskici / Alpay B Seven / Ouliana Panova / Daniel Hilger / Marina Casiraghi / Feng He / Luis Maul / Peter Gmeiner / Brian K Kobilka / Peter W Hildebrand / Georgios Skiniotis /      Abstract: G-protein-coupled receptors (GPCRs) activate heterotrimeric G proteins by stimulating guanine nucleotide exchange in the Gα subunit. To visualize this mechanism, we developed a time-resolved cryo-EM ...G-protein-coupled receptors (GPCRs) activate heterotrimeric G proteins by stimulating guanine nucleotide exchange in the Gα subunit. To visualize this mechanism, we developed a time-resolved cryo-EM approach that examines the progression of ensembles of pre-steady-state intermediates of a GPCR-G-protein complex. By monitoring the transitions of the stimulatory G protein in complex with the β-adrenergic receptor at short sequential time points after GTP addition, we identified the conformational trajectory underlying G-protein activation and functional dissociation from the receptor. Twenty structures generated from sequential overlapping particle subsets along this trajectory, compared to control structures, provide a high-resolution description of the order of main events driving G-protein activation in response to GTP binding. Structural changes propagate from the nucleotide-binding pocket and extend through the GTPase domain, enacting alterations to Gα switch regions and the α5 helix that weaken the G-protein-receptor interface. Molecular dynamics simulations with late structures in the cryo-EM trajectory support that enhanced ordering of GTP on closure of the α-helical domain against the nucleotide-bound Ras-homology domain correlates with α5 helix destabilization and eventual dissociation of the G protein from the GPCR. These findings also highlight the potential of time-resolved cryo-EM as a tool for mechanistic dissection of GPCR signalling events. | |||||||||
