HIV-1 Vpr: A Closer Look at the Multifunctional Protein from the Structural Perspective

Abstract excerpt

The human immunodeficiency virus-1 (HIV-1) Vpr protein plays multiple roles in HIV-1 replication. In early infection, Vpr provides help in the nuclear localization of pre-integration complex. Subsequently, Vpr induces cell cycle arrest of infected cells at G2/M phase. Cell cycle arrest facilitates higher rate of viral gene transcription. Vpr is also capable of activating transcription of viral and heterologous...
