A distinct variant, the tri-heteromeric receptor, ... Discrete activation of N-methyl-D-aspartate receptor (NMDAR) subtypes by glutamate and the co-agonist glycine is fundamental to neuroplasticity. A distinct variant, the tri-heteromeric receptor, comprising glycine-binding GluN1 and two types of glutamate-binding GluN2 subunits, exhibits unique pharmacological characteristics, notably enhanced sensitivity to the anti-depressant channel blocker S-(+)-ketamine. Despite its significance, the structural mechanisms underlying ligand gating and channel blockade of tri-heteromeric NMDARs remain poorly understood. Here, we identify and characterize tri-heteromeric GluN1-2B-2D NMDAR in the adult brain, resolving its structures in the activated, inhibited, and S-(+)-ketamine-blocked states. These structures reveal the ligand-dependent conformational dynamics that modulate the tension between the extracellular domain and transmembrane channels, governing channel gating and blockade. Additionally, we demonstrate that the inhibitor (S)-DQP-997-74 selectively decouples linker tension in GluN2D, offering insights into subtype-selective targeting for cognitive modulation. 履歴 登録 2024年8月9日 - ヘッダ(付随情報) 公開 2025年2月26日 - マップ公開 2025年2月26日 - 更新 2025年4月16日 - 現状 2025年4月16日 処理サイト : RCSB / 状態 : 公開
