The C-Terminal Proline-Rich Tail of Human Immunodeficiency Virus Type 2 Vpx Is Necessary for Nuclear Localization of the Viral Preintegration Complex in Nondividing Cells

Abstract excerpt

Human immunodeficiency virus type 2 (HIV-2), like other lentiviruses, is capable of infecting nondividing T cells and macrophages. The present work shows that in HIV-2-infected cells, Vpx is necessary for efficient nuclear import of the preintegration complex. In agreement with this finding, the subcellular localization of a GFP-Vpx fusion protein was found to be predominantly nuclear. However, deletion of the...
