Abstract

ABSTRACT Viral protein R (Vpr) of human immunodeficiency virus type 1 (HIV-1) is a small accessory protein involved in the nuclear import of viral DNA and the growth arrest of host cells. Several studies have demonstrated that a significant amount of Vpr is incorporated into the virus particle via interaction with the p6 domain of Gag, and it is generally assumed that Vpr is packaged in equimolar ratio to Gag. We have quantitated the relative amount of Vpr in purified virions following [ 35 S]cysteine labeling of infected MT-4 cells, as well as by quantitative immunoblotting and found that Vpr is present in a molar ratio of approximately 1:7 compared to capsid. Analysis of isolated core particles showed that Vpr is associated with the mature viral core, despite quantitative loss of p6 from core preparations. Metabolic labeling of infected cells with ortho[ 32 P]phosphate revealed that a small fraction of Vpr is phosphorylated in virions and infected cells.
