Human immunodeficiency virus type 1 viral protein R localization in infected cells and virions

Abstract

The subcellular localization of human immunodeficiency virus type 1 (HIV-1) viral protein R (Vpr) was examined by subcellular fractionation. In HIV-1-infected peripheral blood mononuclear cells, Vpr was found in the nuclear and membrane fractions as well as the conditioned medium. Expression of Vpr without other HIV-1 proteins, in two different eukaryotic expression systems, demonstrated a predominant localization of Vpr in the nuclear matrix and chromatin extract fractions. Deletion of the carboxyl-terminal 19-amino-acid arginine-rich sequence impaired Vpr nuclear localization. Indirect immunofluorescence confirmed the nuclear localization of Vpr and also indicated a perinuclear location. Expression of Vpr alone did not result in export of the protein from the cell, but when coexpressed with the Gag protein, Vpr was exported and found in virus-like particles. A truncated Gag protein, missing the p6 sequence and a portion of the p9 sequence, was incapable of exporting Vpr from the cell. Regulation of Vpr localization may be important in the influence of this protein on virus replication.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
