![]() | ![]() タイトル: Distinct structure and gating mechanism in diverse NMDA receptors with GluN2C and GluN2D subunits. 著者: Jilin Zhang / Ming Zhang / Qinrui Wang / Han Wen / Zheyi Liu / Fangjun Wang / Yuhang Wang / Fenyong Yao / Nan Song / Zengwei Kou / Yang Li / Fei Guo / Shujia Zhu / ![]() 要旨: N-methyl-D-aspartate (NMDA) receptors are heterotetramers comprising two GluN1 and two alternate GluN2 (N2A-N2D) subunits. Here we report full-length cryo-EM structures of the human N1-N2D di- ...N-methyl-D-aspartate (NMDA) receptors are heterotetramers comprising two GluN1 and two alternate GluN2 (N2A-N2D) subunits. Here we report full-length cryo-EM structures of the human N1-N2D di-heterotetramer (di-receptor), rat N1-N2C di-receptor and N1-N2A-N2C tri-heterotetramer (tri-receptor) at a best resolution of 3.0 Å. The bilobate N-terminal domain (NTD) in N2D intrinsically adopts a closed conformation, leading to a compact NTD tetramer in the N1-N2D receptor. Additionally, crosslinking the ligand-binding domain (LBD) of two N1 protomers significantly elevated the channel open probability (Po) in N1-N2D di-receptors. Surprisingly, the N1-N2C di-receptor adopted both symmetric (minor) and asymmetric (major) conformations, the latter further locked by an allosteric potentiator, PYD-106, binding to a pocket between the NTD and LBD in only one N2C protomer. Finally, the N2A and N2C subunits in the N1-N2A-N2C tri-receptor display a conformation close to one protomer in the N1-N2A and N1-N2C di-receptors, respectively. These findings provide a comprehensive structural understanding of diverse function in major NMDA receptor subtypes. #1: ![]() タイトル: Distinct structure and gating mechanism in diverse NMDA receptors with GluN2C and GluN2D subunits 著者: Zhang, M. / Zhu, S. | ||||||
