Abstract Background Although APOBEC3G protein is a potent and innate anti-HIV-1 cellular factor HIV-1 Vif counteracts the effect of APOBEC3G by promoting its degradation through proteasome-mediated proteolysis. Thus any means that could prevent APOBEC3G degradation could potentially enhance its anti-viral effect. The UBA2 domain has been identified as an intrinsic stabilization signal that protects protein from proteasomal degradation. In this pilot study we tested whether APOBEC3G when it is fused with UBA2 can resist Vif-mediated proteasomal degradation and further inhibit HIV-1 .
