Excitatory signaling mediated by N-methyl-D-aspartate receptor (NMDAR) is critical for brain development and function, as well as for neurological diseases and disorders. Channel blockers of NMDARs are of medical interest owing to their potential for treating depression, Alzheimer's disease, and epilepsy. However, precise mechanisms underlying binding and channel blockade have remained limited owing to challenges in obtaining high-resolution structures at the binding site within the transmembrane domains. Here, we monitor the binding of three clinically important channel blockers: phencyclidine, ketamine, and memantine in GluN1-2B NMDARs at local resolutions of 2.5-3.5 Å around the binding site using single-particle electron cryo-microscopy, molecular dynamics simulations, and electrophysiology. The channel blockers form different extents of interactions with the pore-lining residues, which control mostly off-speeds but not on-speeds. Our comparative analyses of the three unique NMDAR channel blockers provide a blueprint for developing therapeutic compounds with minimal side effects. 履歴 登録 2021年9月22日 登録サイト : RCSB / 処理サイト : RCSB改定 1.0 2022年7月20日 Provider : repository / タイプ : Initial release改定 1.1 2024年11月13日 Group : Data collection / Structure summaryカテゴリ : chem_comp_atom / chem_comp_bond ... chem_comp_atom / chem_comp_bond / em_admin / pdbx_entry_details / pdbx_modification_feature Item : _em_admin.last_update / _pdbx_entry_details.has_protein_modification
