The Ebola virus glycoprotein mucin-like domain (MLD) is implicated in Ebola virus cell entry and immune evasion. Using cryo-electron tomography of Ebola virus-like particles, we determined a three-dimensional structure for the full-length glycoprotein in a near-native state and compared it to that of a glycoprotein lacking the MLD. Our results, which show that the MLD is located at the apex and the sides of each glycoprotein monomer, provide a structural template for analysis of MLD function.
埃博拉病毒糖蛋白粘蛋白样结构域(MLD)与埃博拉病毒进入细胞及免疫逃逸有关。通过对埃博拉病毒样颗粒进行冷冻电子断层扫描,我们确定了全长糖蛋白在近天然状态下的三维结构,并将其与缺乏MLD的糖蛋白结构进行比较。我们的结果表明,MLD位于每个糖蛋白单体的顶端和侧面,为分析MLD功能提供了结构模板。
