タイトル: Structure of the human epithelial sodium channel by cryo-electron microscopy.
著者: Sigrid Noreng / Arpita Bharadwaj / Richard Posert / Craig Yoshioka / Isabelle Baconguis /
要旨: The epithelial sodium channel (ENaC), a member of the ENaC/DEG superfamily, regulates Na and water homeostasis. ENaCs assemble as heterotrimeric channels that harbor protease-sensitive domains ...The epithelial sodium channel (ENaC), a member of the ENaC/DEG superfamily, regulates Na and water homeostasis. ENaCs assemble as heterotrimeric channels that harbor protease-sensitive domains critical for gating the channel. Here, we present the structure of human ENaC in the uncleaved state determined by single-particle cryo-electron microscopy. The ion channel is composed of a large extracellular domain and a narrow transmembrane domain. The structure reveals that ENaC assembles with a 1:1:1 stoichiometry of α:β:γ subunits arranged in a counter-clockwise manner. The shape of each subunit is reminiscent of a hand with key gating domains of a 'finger' and a 'thumb.' Wedged between these domains is the elusive protease-sensitive inhibitory domain poised to regulate conformational changes of the 'finger' and 'thumb'; thus, the structure provides the first view of the architecture of inhibition of ENaC.

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。
