引用ジャーナル : Commun Biol / 年 : 2024タイトル : A conformational selection mechanism of flavivirus NS5 for species-specific STAT2 inhibition.著者 : Mahamaya Biswal / Wangyuan Yao / Jiuwei Lu / Jianbin Chen / Juliet Morrison / Rong Hai / Jikui Song / 要旨 : Flaviviruses, including Zika virus (ZIKV) and Dengue virus (DENV), rely on their non-structural protein 5 (NS5) for both replication of viral genome and suppression of host IFN signaling. DENV and ... Flaviviruses, including Zika virus (ZIKV) and Dengue virus (DENV), rely on their non-structural protein 5 (NS5) for both replication of viral genome and suppression of host IFN signaling. DENV and ZIKV NS5s were shown to facilitate proteosome-mediated protein degradation of human STAT2 (hSTAT2). However, how flavivirus NS5s have evolved for species-specific IFN-suppression remains unclear. Here we report structure-function characterization of the DENV serotype 2 (DENV2) NS5-hSTAT2 complex. The MTase and RdRP domains of DENV2 NS5 form an extended conformation to interact with the coiled-coil and N-terminal domains of hSTAT2, thereby promoting hSTAT2 degradation in cells. Disruption of the extended conformation of DENV2/ZIKV NS5, but not the alternative compact state, impaired their hSTAT2 binding. Our comparative structural analysis of flavivirus NS5s further reveals a conserved protein-interaction platform with subtle amino-acid variations likely underpinning diverse IFN-suppression mechanisms. Together, this study uncovers a conformational selection mechanism underlying species-specific hSTAT2 inhibition by flavivirus NS5. 履歴 登録 2023年6月1日 - ヘッダ(付随情報) 公開 2024年1月17日 - マップ公開 2024年1月17日 - 更新 2024年7月31日 - 現状 2024年7月31日 処理サイト : RCSB / 状態 : 公開
