引用ジャーナル : Nature / 年 : 2019タイトル : Cryo-EM structures of apo and antagonist-bound human Ca3.1.著者 : Yanyu Zhao / Gaoxingyu Huang / Qiurong Wu / Kun Wu / Ruiqi Li / Jianlin Lei / Xiaojing Pan / Nieng Yan / 要旨 : Among the ten subtypes of mammalian voltage-gated calcium (Ca) channels, Ca3.1-Ca3.3 constitute the T-type, or the low-voltage-activated, subfamily, the abnormal activities of which are associated ... Among the ten subtypes of mammalian voltage-gated calcium (Ca) channels, Ca3.1-Ca3.3 constitute the T-type, or the low-voltage-activated, subfamily, the abnormal activities of which are associated with epilepsy, psychiatric disorders and pain. Here we report the cryo-electron microscopy structures of human Ca3.1 alone and in complex with a highly Ca3-selective blocker, Z944, at resolutions of 3.3 Å and 3.1 Å, respectively. The arch-shaped Z944 molecule reclines in the central cavity of the pore domain, with the wide end inserting into the fenestration on the interface between repeats II and III, and the narrow end hanging above the intracellular gate like a plug. The structures provide the framework for comparative investigation of the distinct channel properties of different Ca subfamilies. 履歴 登録 2019年9月25日 登録サイト : PDBJ / 処理サイト : PDBJ改定 1.0 2019年12月18日 Provider : repository / タイプ : Initial release改定 1.1 2020年1月1日 Group : Database references / カテゴリ : citationItem : _citation.journal_volume / _citation.page_first / _citation.page_last改定 1.2 2020年7月29日 Group : Data collection / Derived calculations / Structure summaryカテゴリ : chem_comp / entity ... chem_comp / entity / pdbx_chem_comp_identifier / pdbx_entity_nonpoly / struct_conn / struct_site / struct_site_gen Item : _chem_comp.name / _chem_comp.type ... _chem_comp.name / _chem_comp.type / _entity.pdbx_description / _pdbx_entity_nonpoly.name / _struct_conn.conn_type_id / _struct_conn.id / _struct_conn.pdbx_dist_value / _struct_conn.pdbx_leaving_atom_flag / _struct_conn.pdbx_role / _struct_conn.ptnr1_auth_comp_id / _struct_conn.ptnr1_auth_seq_id / _struct_conn.ptnr1_label_atom_id / _struct_conn.ptnr1_label_comp_id / _struct_conn.ptnr1_label_seq_id / _struct_conn.ptnr2_auth_comp_id / _struct_conn.ptnr2_auth_seq_id / _struct_conn.ptnr2_label_asym_id / _struct_conn.ptnr2_label_atom_id / _struct_conn.ptnr2_label_comp_id 解説 : Carbohydrate remediation / Provider : repository / タイプ : Remediation改定 1.3 2024年10月30日 Group : Data collection / Database references ...
