引用ジャーナル : Cell / 年 : 2017タイトル : Activation and Desensitization Mechanism of AMPA Receptor-TARP Complex by Cryo-EM.著者 : Shanshuang Chen / Yan Zhao / Yuhang Wang / Mrinal Shekhar / Emad Tajkhorshid / Eric Gouaux / 要旨 : AMPA receptors mediate fast excitatory neurotransmission in the mammalian brain and transduce the binding of presynaptically released glutamate to the opening of a transmembrane cation channel. ... AMPA receptors mediate fast excitatory neurotransmission in the mammalian brain and transduce the binding of presynaptically released glutamate to the opening of a transmembrane cation channel. Within the postsynaptic density, however, AMPA receptors coassemble with transmembrane AMPA receptor regulatory proteins (TARPs), yielding a receptor complex with altered gating kinetics, pharmacology, and pore properties. Here, we elucidate structures of the GluA2-TARP γ2 complex in the presence of the partial agonist kainate or the full agonist quisqualate together with a positive allosteric modulator or with quisqualate alone. We show how TARPs sculpt the ligand-binding domain gating ring, enhancing kainate potency and diminishing the ensemble of desensitized states. TARPs encircle the receptor ion channel, stabilizing M2 helices and pore loops, illustrating how TARPs alter receptor pore properties. Structural and computational analysis suggests the full agonist and modulator complex harbors an ion-permeable channel gate, providing the first view of an activated AMPA receptor. 履歴 登録 2017年5月3日 登録サイト : RCSB / 処理サイト : RCSB改定 1.0 2017年7月12日 Provider : repository / タイプ : Initial release改定 1.1 2017年9月20日 Group : Author supporting evidence / Data collectionカテゴリ : em_image_scans / em_software / pdbx_audit_supportItem : _em_software.name / _pdbx_audit_support.funding_organization改定 1.2 2017年10月4日 Group : Database references / カテゴリ : citation / citation_authorItem : _citation.journal_abbrev / _citation.journal_id_CSD ... _citation.journal_abbrev / _citation.journal_id_CSD / _citation.journal_id_ISSN / _citation.journal_volume / _citation.page_first / _citation.page_last / _citation.pdbx_database_id_DOI / _citation.pdbx_database_id_PubMed / _citation.title / _citation.year / _citation_author.name 改定 1.3 2017年11月8日 Group : Derived calculations / カテゴリ : pdbx_struct_assemblyItem : _pdbx_struct_assembly.details / _pdbx_struct_assembly.method_details改定 1.4 2018年7月18日 Group : Data collection / カテゴリ : em_software / Item : _em_software.name改定 1.5 2019年11月6日 Group : Data collection / Other / Structure summaryカテゴリ : atom_sites / cell ... atom_sites / cell / em_entity_assembly / struct Item : _atom_sites.fract_transf_matrix[1][1] / _atom_sites.fract_transf_matrix[2][2] ... _atom_sites.fract_transf_matrix[1][1] / _atom_sites.fract_transf_matrix[2][2] / _atom_sites.fract_transf_matrix[3][3] / _cell.Z_PDB / _cell.length_a / _cell.length_b / _cell.length_c / _em_entity_assembly.entity_id_list / _struct.title 改定 1.6 2019年12月18日 Group : Author supporting evidence / カテゴリ : pdbx_audit_support / Item : _pdbx_audit_support.funding_organization改定 1.7 2024年10月30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 / em_author_list / pdbx_entry_details / pdbx_modification_feature Item : _database_2.pdbx_DOI / _database_2.pdbx_database_accession / _em_admin.last_update
