To elucidate the ... Rhodopsin (Rho), a prototypical G-protein-coupled receptor (GPCR) in vertebrate vision, activates the G-protein transducin (G) by catalyzing GDP-GTP exchange on its α subunit (Gα). To elucidate the determinants of G coupling and activation, we obtained cryo-EM structures of a fully functional, light-activated Rho-G complex in the presence and absence of a G-protein-stabilizing nanobody. The structures illustrate how G overcomes its low basal activity by engaging activated Rho in a conformation distinct from other GPCR-G-protein complexes. Moreover, the nanobody-free structures reveal native conformations of G-protein components and capture three distinct conformers showing the Gα helical domain (αHD) contacting the Gβγ subunits. These findings uncover the molecular underpinnings of G-protein activation by visual rhodopsin and shed new light on the role played by Gβγ during receptor-catalyzed nucleotide exchange. 履歴 登録 2019年5月14日 登録サイト : RCSB / 処理サイト : RCSB改定 1.0 2019年7月24日 Provider : repository / タイプ : Initial release改定 1.1 2019年9月4日 Group : Data collection / Database references / カテゴリ : citation / Item : _citation.journal_volume / _citation.page_first改定 1.2 2019年11月27日 Group : Data collection / カテゴリ : em_software / Item : _em_software.name改定 1.3 2019年12月4日 Group : Author supporting evidence / カテゴリ : pdbx_audit_support / Item : _pdbx_audit_support.funding_organization改定 1.4 2024年11月6日 Group : Data collection / Database references / Structure summaryカテゴリ : chem_comp_atom / chem_comp_bond ... chem_comp_atom / chem_comp_bond / database_2 / em_admin / pdbx_entry_details / pdbx_modification_feature Item : _database_2.pdbx_DOI / _database_2.pdbx_database_accession / _em_admin.last_update
