HIV-1 Vpr-induced DNA damage activates NF-κB through ATM-NEMO independent of cell cycle arrest

Abstract excerpt

ABSTRACT Lentiviruses encode a number of multi-functional accessory proteins, however, the primary role of the accessory protein Vpr remains unclear. As Vpr engages the host DNA damage response (DDR) at multiple steps, modulation of the DDR is considered central to the function(s) of Vpr. Vpr activates ataxia telangiectasia and Rad3 (ATR)-mediated DDR signaling, resulting in cell cycle arrest. However, the...
