ABCB1, also known as P-glycoprotein, actively extrudes xenobiotic compounds across the plasma membrane of diverse cells, which contributes to cellular drug resistance and interferes with therapeutic drug delivery. We determined the 3.5-angstrom cryo-electron microscopy structure of substrate-bound human ABCB1 reconstituted in lipidic nanodiscs, revealing a single molecule of the chemotherapeutic compound paclitaxel (Taxol) bound in a central, occluded pocket. A second structure of inhibited, human-mouse chimeric ABCB1 revealed two molecules of zosuquidar occupying the same drug-binding pocket. Minor structural differences between substrate- and inhibitor-bound ABCB1 sites are amplified toward the nucleotide-binding domains (NBDs), revealing how the plasticity of the drug-binding site controls the dynamics of the adenosine triphosphate-hydrolyzing NBDs. Ordered cholesterol and phospholipid molecules suggest how the membrane modulates the conformational changes associated with drug binding and transport. 履歴 登録 2019年1月8日 登録サイト : PDBE / 処理サイト : PDBE改定 1.0 2019年2月27日 Provider : repository / タイプ : Initial release改定 1.1 2019年12月18日 Group : 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 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.pdbx_role 解説 : Carbohydrate remediation / Provider : repository / タイプ : Remediation改定 1.3 2021年6月2日 Group : Structure summary / カテゴリ : chem_comp / Item : _chem_comp.pdbx_synonyms改定 1.4 2024年11月13日 Group : Data collection / Database references ...
