Histamine exerts critical physiological roles by activating four receptor subtypes, each exhibiting a specific G protein preference. Among these, the histamine H receptor (HR) modulates chemotaxis and interferon production through G protein activation, suggesting its therapeutic potential. Despite its physiological significance, the mechanisms underlying HR signalling and G protein preference across histamine receptors remain poorly understood. Here, we present the cryo-electron microscopy structure of the HR-G complex, revealing unique mechanisms of histamine recognition and receptor activation. We further solved the structures of the histamine H receptor (HR) bound to the non-canonical G proteins G and G. Through a combination of functional and computational analyses, we identified the intracellular loop 2 as a critical determinant of G protein preference in HR and HR. Collectively, our comprehensive study revealed the structural basis for distinct mechanisms of ligand recognition and receptor activation, offering a profound insight into G protein preference across receptor subtypes. 履歴 登録 2025年1月30日 登録サイト : PDBJ / 処理サイト : PDBJ改定 1.0 2025年6月11日 Provider : repository / タイプ : Initial release改定 1.0 2025年6月11日 Data content type : EM metadata / Data content type : EM metadata / Provider : repository / タイプ : Initial release改定 1.0 2025年6月11日 Data content type : Half map / Part number : 1 / Data content type : Half map / Provider : repository / タイプ : Initial release改定 1.0 2025年6月11日 Data content type : Half map / Part number : 2 / Data content type : Half map / Provider : repository / タイプ : Initial release改定 1.0 2025年6月11日 Data content type : Image / Data content type : Image / Provider : repository / タイプ : Initial release改定 1.0 2025年6月11日 Data content type : Mask / Part number : 1 / Data content type : Mask / Provider : repository / タイプ : Initial release改定 1.0 2025年6月11日 Data content type : Primary map / Data content type : Primary map / Provider : repository / タイプ : Initial release改定 1.1 2025年7月23日 Group : Data collection / Database references / カテゴリ : citation / em_adminItem : _citation.country / _citation.journal_abbrev ... _citation.country / _citation.journal_abbrev / _citation.journal_id_CSD / _citation.journal_id_ISSN / _citation.journal_volume / _citation.page_first / _citation.page_last / _citation.pdbx_database_id_DOI / _citation.pdbx_database_id_PubMed / _citation.title / _citation.year / _em_admin.last_update
