引用ジャーナル : Science / 年 : 2019タイトル : Structural insight into substrate and inhibitor discrimination by human P-glycoprotein.著者 : Amer Alam / Julia Kowal / Eugenia Broude / Igor Roninson / Kaspar P Locher / 要旨 : 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 ... 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 - ヘッダ(付随情報) 公開 2019年2月27日 - マップ公開 2019年2月27日 - 更新 2024年11月13日 - 現状 2024年11月13日 処理サイト : PDBe / 状態 : 公開
