TGF-β, essential for development and immunity, is expressed as a latent complex (L-TGF-β) non-covalently associated with its prodomain and presented on immune cell surfaces by covalent association with GARP. Binding to integrin αvβ8 activates L-TGF-β1/GARP. The dogma is that mature TGF-β must physically dissociate from L-TGF-β1 for signaling to occur. Our previous studies discovered that αvβ8-mediated TGF-β autocrine signaling can occur without TGF-β1 release from its latent form. Here, we show that mice engineered to express TGF-β1 that cannot release from L-TGF-β1 survive without early lethal tissue inflammation, unlike those with TGF-β1 deficiency. Combining cryogenic electron microscopy with cell-based assays, we reveal a dynamic allosteric mechanism of autocrine TGF-β1 signaling without release where αvβ8 binding redistributes the intrinsic flexibility of L-TGF-β1 to expose TGF-β1 to its receptors. Dynamic allostery explains the TGF-β3 latency/activation mechanism and why TGF-β3 functions distinctly from TGF-β1, suggesting that it broadly applies to other flexible cell surface receptor/ligand systems. 履歴 登録 2024年1月23日 登録サイト : RCSB / 処理サイト : RCSB改定 1.0 2024年9月11日 Provider : repository / タイプ : Initial release改定 1.1 2024年10月2日 Group : Data collection / Database references / カテゴリ : citation / citation_author / em_adminItem : _citation.country / _citation.journal_abbrev ... _citation.country / _citation.journal_abbrev / _citation.journal_id_ASTM / _citation.journal_id_CSD / _citation.journal_id_ISSN / _citation.pdbx_database_id_DOI / _citation.pdbx_database_id_PubMed / _citation.title / _em_admin.last_update 改定 1.2 2024年11月13日 Group : Data collection / Database references / Structure summaryカテゴリ : citation / em_admin ... citation / em_admin / pdbx_entry_details / pdbx_modification_feature Item : _citation.journal_volume / _citation.page_first ... _citation.journal_volume / _citation.page_first / _citation.page_last / _em_admin.last_update / _pdbx_entry_details.has_protein_modification 改定 1.3 2024年11月20日 Group : Data collection / Database references / カテゴリ : citation / em_admin / Item : _citation.page_last / _em_admin.last_update
