タイトル: Architecture and subunit arrangement of native AMPA receptors elucidated by cryo-EM.

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.

2019年1月31日: EMDBのIDの桁数の変更

EMDBのIDの桁数の変更

  • EMDBエントリに付与されているアクセスコード(EMDB-ID)は4桁の数字(例、EMD-1234)でしたが、間もなく枯渇します。これまでの4桁のID番号は4桁のまま変更されませんが、4桁の数字を使い切った後に発行されるIDは5桁以上の数字(例、EMD-12345)になります。5桁のIDは2019年の春頃から発行される見通しです。
  • EM Navigator/万見では、接頭語「EMD-」は省略されています。

2017年7月12日: PDB大規模アップデート

PDB大規模アップデート

  • 新バージョンのPDBx/mmCIF辞書形式に基づくデータがリリースされました。
  • 今回の更新はバージョン番号が4から5になる大規模なもので、全エントリデータの書き換えが行われる「Remediation」というアップデートに該当します。
  • このバージョンアップで、電子顕微鏡の実験手法に関する多くの項目の書式が改定されました(例：em_softwareなど)。
  • EM NavigatorとYorodumiでも、この改定に基づいた表示内容になります。

外部リンク:wwPDB Remediation / OneDepデータ基準に準拠した、より強化された内容のモデル構造ファイルが、PDBアーカイブで公開されました。
