引用ジャーナル : Mol Cell / 年 : 2021タイトル : ISRIB Blunts the Integrated Stress Response by Allosterically Antagonising the Inhibitory Effect of Phosphorylated eIF2 on eIF2B.著者: Alisa F Zyryanova / Kazuhiro Kashiwagi / Claudia Rato / Heather P Harding / Ana Crespillo-Casado / Luke A Perera / Ayako Sakamoto / Madoka Nishimoto / Mayumi Yonemochi / Mikako Shirouzu / ... 著者 : Alisa F Zyryanova / Kazuhiro Kashiwagi / Claudia Rato / Heather P Harding / Ana Crespillo-Casado / Luke A Perera / Ayako Sakamoto / Madoka Nishimoto / Mayumi Yonemochi / Mikako Shirouzu / Takuhiro Ito / David Ron / 要旨 : The small molecule ISRIB antagonizes the activation of the integrated stress response (ISR) by phosphorylated translation initiation factor 2, eIF2(αP). ISRIB and eIF2(αP) bind distinct sites in ... The small molecule ISRIB antagonizes the activation of the integrated stress response (ISR) by phosphorylated translation initiation factor 2, eIF2(αP). ISRIB and eIF2(αP) bind distinct sites in their common target, eIF2B, a guanine nucleotide exchange factor for eIF2. We have found that ISRIB-mediated acceleration of eIF2B's nucleotide exchange activity in vitro is observed preferentially in the presence of eIF2(αP) and is attenuated by mutations that desensitize eIF2B to the inhibitory effect of eIF2(αP). ISRIB's efficacy as an ISR inhibitor in cells also depends on presence of eIF2(αP). Cryoelectron microscopy (cryo-EM) showed that engagement of both eIF2B regulatory sites by two eIF2(αP) molecules remodels both the ISRIB-binding pocket and the pockets that would engage eIF2α during active nucleotide exchange, thereby discouraging both binding events. In vitro, eIF2(αP) and ISRIB reciprocally opposed each other's binding to eIF2B. These findings point to antagonistic allostery in ISRIB action on eIF2B, culminating in inhibition of the ISR. 履歴 登録 2020年9月22日 登録サイト : PDBJ / 処理サイト : PDBJ改定 1.0 2020年12月9日 Provider : repository / タイプ : Initial release改定 1.1 2021年1月27日 Group : Database references / カテゴリ : citationItem : _citation.journal_volume / _citation.page_first / _citation.year改定 1.2 2024年10月30日 Group : Data collection / Database references / Structure summaryカテゴリ : chem_comp_atom / chem_comp_bond ... chem_comp_atom / chem_comp_bond / database_2 / em_admin / pdbx_entry_details / pdbx_modification_feature Item : _database_2.pdbx_DOI / _database_2.pdbx_database_accession ... _database_2.pdbx_DOI / _database_2.pdbx_database_accession / _em_admin.last_update / _pdbx_entry_details.has_protein_modification
