引用ジャーナル : Science / 年 : 2019タイトル : Architecture and subunit arrangement of native AMPA receptors elucidated by cryo-EM.著者 : Yan Zhao / Shanshuang Chen / Adam C Swensen / Wei-Jun Qian / Eric Gouaux / 要旨 : Glutamate-gated AMPA receptors mediate the fast component of excitatory signal transduction at chemical synapses throughout all regions of the mammalian brain. AMPA receptors are tetrameric ... Glutamate-gated AMPA receptors mediate the fast component of excitatory signal transduction at chemical synapses throughout all regions of the mammalian brain. AMPA receptors are tetrameric assemblies composed of four subunits, GluA1-GluA4. Despite decades of study, the subunit composition, subunit arrangement, and molecular structure of native AMPA receptors remain unknown. Here we elucidate the structures of 10 distinct native AMPA receptor complexes by single-particle cryo-electron microscopy (cryo-EM). We find that receptor subunits are arranged nonstochastically, with the GluA2 subunit preferentially occupying the B and D positions of the tetramer and with triheteromeric assemblies comprising a major population of native AMPA receptors. Cryo-EM maps define the structure for S2-M4 linkers between the ligand-binding and transmembrane domains, suggesting how neurotransmitter binding is coupled to ion channel gating. 履歴 登録 2021年1月13日 - ヘッダ(付随情報) 公開 2021年5月12日 - マップ公開 2021年5月12日 - 更新 2024年10月16日 - 現状 2024年10月16日 処理サイト : RCSB / 状態 : 公開
