Vpr has several roles in the progression of acquired immunodeficiency syndrome (AIDS in Wikipedia ) disease, including regulation the HIV-1 pre-integration complex (Pre-integration_complex in Wikipedia ) nuclear import and virus replication in non-dividing macrophages. Moreover, Vpr prevents mitosis of dividing infect cells by blockade at G2 phase, when the viral promoter is more active, and induced apoptosis of these cells in G1 and M phase. For details see HIV and accessory proteins. Disease Vpr is essential for HIV-1 replication in proliferating and non-dividing cells.
