摘要:
通过构建突变型蛋白表达质粒,将乙型肝炎病毒核心蛋白(Hepatitis B virus core protein, HBc)的赖氨酸位点K96突变为谷氨酰胺(Q)或精氨酸(R),以分别模拟HBc的持续性乙酰化状态以及去乙酰化状态,分析赖氨酸位点K96在病毒衣壳组装过程中的关键性作用;通过建立瞬时转染模型,将野生型及突变型核心蛋白表达质粒转染至细胞中,分别检测突变后的核心蛋白的表达水平和衣壳组装水平,比较分析不同突变对衣壳组装的影响。结果表明:阻断赖氨酸位点K96的乙酰化修饰能够抑制HBc的表达,并且显著降低病毒衣壳的组装水平;而赖氨酸位点K96的持续性乙酰化状态对HBc的表达和病毒衣壳组装水平没有显著影响。
