Here, we present the cryo-EM ... The Polycystic Kidney Disease 2 (Pkd2) gene is mutated in autosomal dominant polycystic kidney disease (ADPKD), one of the most common human monogenic disorders. Here, we present the cryo-EM structure of PKD2 in lipid bilayers at 3.0 Å resolution, which establishes PKD2 as a homotetrameric ion channel and provides insight into potential mechanisms for its activation. The PKD2 voltage-sensor domain retains two of four gating charges commonly found in those of voltage-gated ion channels. The PKD2 ion permeation pathway is constricted at the selectivity filter and near the cytoplasmic end of S6, suggesting that two gates regulate ion conduction. The extracellular domain of PKD2, a hotspot for ADPKD pathogenic mutations, contributes to channel assembly and strategically interacts with the transmembrane core, likely serving as a physical substrate for extracellular stimuli to allosterically gate the channel. Finally, our structure establishes the molecular basis for the majority of pathogenic mutations in Pkd2-related ADPKD. 履歴 登録 2016年8月29日 登録サイト : RCSB / 処理サイト : RCSB改定 1.0 2016年11月2日 Provider : repository / タイプ : Initial release改定 1.1 2016年11月9日 Group : Structure summary改定 1.2 2016年11月30日 Group : Structure summary改定 1.3 2017年11月8日 Group : Data processing / Derived calculations / カテゴリ : em_software / pdbx_struct_assemblyItem : _em_software.name / _pdbx_struct_assembly.details / _pdbx_struct_assembly.method_details改定 1.4 2019年11月6日 Group : Data collection / Other / カテゴリ : atom_sites / cellItem : _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 改定 1.5 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.pdbx_role 解説 : Carbohydrate remediation / Provider : repository / タイプ : Remediation
