Fifty-eight million individuals worldwide are affected by chronic hepatitis C virus (HCV) infection, a primary driver of liver cancer for which no vaccine is available. The HCV envelope proteins E1 and E2 form a heterodimer (E1/E2), which is the target for neutralizing antibodies. However, the higher-order organization of these E1/E2 heterodimers, as well as that of any Hepacivirus envelope protein complex, remains unknown. Here we determined the cryo-electron microscopy structure of two E1/E2 heterodimers in a homodimeric arrangement. We reveal how the homodimer is established at the molecular level and provide insights into neutralizing antibody evasion and membrane fusion by HCV, as orchestrated by E2 motifs such as hypervariable region 1 and antigenic site 412, as well as the organization of the transmembrane helices, including two internal to E1. This study addresses long-standing questions on the higher-order oligomeric arrangement of Hepacivirus envelope proteins and provides a critical framework in the design of novel HCV vaccine antigens. 履歴 登録 2023年12月22日 - ヘッダ(付随情報) 公開 2024年9月4日 - マップ公開 2024年9月4日 - 更新 2024年10月23日 - 現状 2024年10月23日 処理サイト : PDBe / 状態 : 公開
