APOBEC3G (A3G)—is a potent inhibitor of infection by a range of retroviruses, including HIV. deaminates Cs to produce Us in that DNA strand, leading to hypermutation at levels the virus cannot accommodate, or even to destruction of the damaged strand by DNA glycosylase and apurinic apyrimidinic endonuclease
