Recently, Neuroplastin (NPTN) and basigin were identified as previously ... Plasma membrane Ca-ATPases (PMCAs) are key regulators of global Ca homeostasis and local intracellular Ca dynamics. Recently, Neuroplastin (NPTN) and basigin were identified as previously unrecognized obligatory subunits of PMCAs that dramatically increase the efficiency of PMCA-mediated Ca clearance. Here, we report the cryo-EM structure of human PMCA1 (hPMCA1) in complex with NPTN at a resolution of 4.1 Å for the overall structure and 3.9 Å for the transmembrane domain. The single transmembrane helix of NPTN interacts with the TM-linker and TM10 of hPMCA1. The subunits are required for the hPMCA1 functional activity. The NPTN-bound hPMCA1 closely resembles the E1-Mg structure of endo(sarco)plasmic reticulum Ca ATPase and the Ca site is exposed through a large open cytoplasmic pathway. This structure provides insight into how the subunits bind to the PMCAs and serves as an important basis for understanding the functional mechanisms of this essential calcium pump family. 履歴 登録 2018年6月27日 登録サイト : PDBJ / 処理サイト : PDBJ改定 1.0 2018年9月19日 Provider : repository / タイプ : Initial release改定 1.1 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改定 1.2 2024年11月6日 Group : Data collection / Database references / Structure summaryカテゴリ : chem_comp / chem_comp_atom ... chem_comp / chem_comp_atom / chem_comp_bond / database_2 / em_admin / pdbx_entry_details / pdbx_modification_feature Item : _chem_comp.pdbx_synonyms / _database_2.pdbx_DOI ... _chem_comp.pdbx_synonyms / _database_2.pdbx_DOI / _database_2.pdbx_database_accession / _em_admin.last_update / _pdbx_entry_details.has_protein_modification
