It is involved in nervous system regulation and an attractive target for the treatment of psychosis, depression, schizophrenia, and neuropathic pain. 5-HT is the only G-coupled 5-HT receptor subtype lacking a high-resolution structure, which hampers the mechanistic understanding of ligand binding and G coupling for 5-HT. Here we report a cryo-electron microscopy structure of the 5-HT-G complex bound to 5-Carboxamidotryptamine (5-CT). Combined with functional analysis, this structure reveals the 5-CT recognition mechanism and identifies the receptor residue at 6.55 as a determinant of the 5-CT selectivity for G-coupled 5-HT receptors. In addition, 5-HT shows an overall conserved G protein coupling mode compared with other G-coupled 5-HT receptors. These findings provide comprehensive insights into the ligand binding and G protein coupling of G-coupled 5-HT receptors and offer a template for the design of 5-HT-selective drugs. 履歴 登録 2022年3月4日 登録サイト : PDBJ / 処理サイト : PDBJ改定 1.0 2022年9月14日 Provider : repository / タイプ : Initial release改定 1.1 2022年9月21日 Group : Database references / カテゴリ : citation / citation_authorItem : _citation.journal_volume / _citation.page_first ... _citation.journal_volume / _citation.page_first / _citation.page_last / _citation.pdbx_database_id_PubMed / _citation.title / _citation_author.identifier_ORCID 改定 1.2 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
