Despite ... Cryogenic electron microscopy (cryo-EM) has widened the field of structure-based drug discovery by allowing for routine determination of membrane protein structures previously intractable. Despite representing one of the largest classes of therapeutic targets, most inactive-state G protein-coupled receptors (GPCRs) have remained inaccessible for cryo-EM because their small size and membrane-embedded nature impedes projection alignment for high-resolution map reconstructions. Here we demonstrate that the same single-chain camelid antibody (nanobody) recognizing a grafted intracellular loop can be used to obtain cryo-EM structures of inactive-state GPCRs at resolutions comparable or better than those obtained by X-ray crystallography. Using this approach, we obtained structures of neurotensin 1 receptor bound to antagonist SR48692, μ-opioid receptor bound to alvimopan, apo somatostatin receptor 2 and histamine receptor 2 bound to famotidine. We expect this rapid, straightforward approach to facilitate the broad exploration of GPCR inactive states without the need for extensive engineering and crystallization. 履歴 登録 2022年4月3日 登録サイト : RCSB / 処理サイト : RCSB改定 1.0 2022年6月29日 Provider : repository / タイプ : Initial release改定 1.1 2022年11月23日 Group : Database references / カテゴリ : citationItem : _citation.country / _citation.journal_abbrev ... _citation.country / _citation.journal_abbrev / _citation.journal_id_CSD / _citation.journal_id_ISSN / _citation.pdbx_database_id_DOI / _citation.year 改定 1.2 2022年11月30日 Group : Database references / カテゴリ : citation / Item : _citation.pdbx_database_id_PubMed / _citation.title改定 1.3 2022年12月28日 Group : Database references / カテゴリ : citation / citation_authorItem : _citation.journal_volume / _citation.page_first ... _citation.journal_volume / _citation.page_first / _citation.page_last / _citation_author.identifier_ORCID 改定 1.4 2024年9月25日 Group : Data collection / Source and taxonomyカテゴリ : chem_comp_atom / chem_comp_bond ... chem_comp_atom / chem_comp_bond / em_admin / em_entity_assembly_naturalsource / em_entity_assembly_recombinant Item : _em_admin.last_update / _em_entity_assembly_naturalsource.id / _em_entity_assembly_recombinant.id改定 1.5 2024年10月23日 Group : Data collection / Structure summaryカテゴリ : em_admin / pdbx_entry_details / pdbx_modification_featureItem : _em_admin.last_update
