The physiology of N-methyl-d-aspartate (NMDA) receptors is fundamental to brain development and function. NMDA receptors are ionotropic glutamate receptors that function as heterotetramers composed mainly of GluN1 and GluN2 subunits. Activation of NMDA receptors requires binding of neurotransmitter agonists to a ligand-binding domain (LBD) and structural rearrangement of an amino-terminal domain (ATD). Recent crystal structures of GluN1-GluN2B NMDA receptors bound to agonists and an allosteric inhibitor, ifenprodil, represent the allosterically inhibited state. However, how the ATD and LBD move to activate the NMDA receptor ion channel remains unclear. Here we applied X-ray crystallography, single-particle electron cryomicroscopy and electrophysiology to rat NMDA receptors to show that, in the absence of ifenprodil, the bi-lobed structure of GluN2 ATD adopts an open conformation accompanied by rearrangement of the GluN1-GluN2 ATD heterodimeric interface, altering subunit orientation in the ATD and LBD and forming an active receptor conformation that gates the ion channel. 履歴 登録 2016年3月1日 登録サイト : PDBJ / 処理サイト : PDBJ改定 1.0 2016年5月11日 Provider : repository / タイプ : Initial release改定 1.1 2016年5月18日 Group : Database references改定 1.2 2016年6月15日 Group : Database references改定 1.3 2017年9月27日 Group : Data collection / Database references / Derived calculationsカテゴリ : citation / diffrn_detector / pdbx_struct_oper_listItem : _citation.journal_id_CSD / _diffrn_detector.detector / _pdbx_struct_oper_list.symmetry_operation改定 1.4 2017年10月18日 Group : Author supporting evidence / カテゴリ : pdbx_audit_support / Item : _pdbx_audit_support.funding_organization改定 1.5 2022年3月23日 Group : Author supporting evidence / Database references / カテゴリ : database_2 / pdbx_audit_supportItem : _database_2.pdbx_DOI / _database_2.pdbx_database_accession / _pdbx_audit_support.funding_organization改定 1.6 2024年10月23日 Group : Data collection / Structure summaryカテゴリ : chem_comp_atom / chem_comp_bond ... chem_comp_atom / chem_comp_bond / pdbx_entry_details / pdbx_modification_feature
