Abstract:
:The human immunodeficiency virus type 1 Vpr protein is both packaged into virions and efficiently localized to the nucleus. In this report, we show that a significant fraction of Vpr also accumulates in the cytoplasm of virus-producing cells. Although Vpr shuttles between the nucleus and the cytoplasm, studies with an export-deficient Vpr mutant reveal that nuclear export is not required for virion incorporation.
