Abstract
The HIV-1 Vpr protein is a viral accessory protein that plays a number of important roles during HIV infection. The activities of Vpr are numerous and include the induction of apoptosis, the modulation of cell cycle arrest, as well as control of viral transcription. Study of HIV clones lacking Vpr in vitro and analysis of HIV variants isolated from longterm nonprogressors in vivo highlight the importance of Vpr for viral replication as well as immune suppression and cell death. Vpr may therefore be considered among the most important accessory proteins encoded by HIV.
