CONT

A real difference in pathogenicity between HIV-1 and HIV-2 could be significant, and it would be important to determine its molecular basis. The two viruses infect the same populations of cells, binding the same CD4 receptor, but there are some differences in their genetic material and therefore in proteins. One of the most obvious is the presence in HIV-1 of the vpu gene, which is absent in HIV- (and in SIV, for that matter).

OBS

Upr stands for viral protein U.

DEF

A 96-amino acid (14 kd) protein, which is incorporated into the virion. It interacts with the p6gag part of the Pr55gag precursor. Vpr detected in the cell is localized to the nucleus. Proposed functions for Vpr include the nuclear import of preintegration complexes, cell growth arrest,transactivation of cellular genes, and induction of cellular differentiation. Found in HIV-1, HIV-2, SIVmac and SIVmnd. It is homologous to VPX of SIVagm.
