HIV-1病毒蛋白R(VpR)是一种多功能蛋白,在HIV-1病毒生命周期的多个阶段发挥特定作用,并影响免疫细胞的抗HIV功能。VpR是非分裂细胞如巨噬细胞中有效病毒复制所必需的,并且在一定程度上促进增殖靶CD 4 + T细胞中的病毒复制。一些具体的活动,可能有助于这些影响的VpR已被提出。在这一章中,我们描述了两个最好的特征活动VpR,核进口的HIV-1前整合复合物(PIC)和诱导细胞周期G2期阻滞,重点是用于演示的方法。
HIV-1 viral protein R (VpR) is a multifunctional protein that plays specific roles at multiple stages of the HIV-1 viral life cycle and affects anti-HIV functions of the immune cells. VpR is required for efficient viral replication in nondividing cells such as macrophages, and it promotes, to some extent, viral replication in the proliferating target CD4+ T cells. A number of specific activities that may contribute to these effects of VpR have been proposed. In this chapter, we describe two best characterized activities of VpR, nuclear import of the HIV-1 preintegration complex (PIC) and induction of cell cycle G2 arrest, focusing on the methods used for their demonstration.
