The strychnine-sensitive pentameric glycine receptor (GlyR) mediates fast inhibitory neurotransmission in the mammalian nervous system. Only heteromeric GlyRs mediate synaptic transmission, as they contain the β subunit that permits clustering at the synapse through its interaction with scaffolding proteins. Here, we show that α2 and β subunits assemble with an unexpected 4:1 stoichiometry to produce GlyR with native electrophysiological properties. We determined structures in multiple functional states at 3.6-3.8 Å resolutions and show how 4:1 stoichiometry is consistent with the structural features of α2β GlyR. Furthermore, we show that one single β subunit in each GlyR gives rise to the characteristic electrophysiological properties of heteromeric GlyR, while more β subunits render GlyR non-conductive. A single β subunit ensures a univalent GlyR-scaffold linkage, which means the scaffold alone regulates the cluster properties. 履歴 登録 2020年12月17日 登録サイト : RCSB / 処理サイト : RCSB改定 1.0 2021年9月8日 Provider : repository / タイプ : Initial release改定 1.1 2024年11月6日 Group : Data collection / Refinement description / Structure summaryカテゴリ : chem_comp_atom / chem_comp_bond ... chem_comp_atom / chem_comp_bond / em_3d_fitting_list / em_admin / pdbx_entry_details / pdbx_initial_refinement_model / pdbx_modification_feature Item : _em_3d_fitting_list.accession_code / _em_3d_fitting_list.initial_refinement_model_id ... _em_3d_fitting_list.accession_code / _em_3d_fitting_list.initial_refinement_model_id / _em_3d_fitting_list.source_name / _em_3d_fitting_list.type / _em_admin.last_update / _pdbx_entry_details.has_protein_modification
