APOBEC3G (apolipoprotein B mRNA-editing enzyme-catalytic polypeptide-like 3G) is a human enzyme encoded by the APOBEC3G gene that belongs to the APOBEC superfamily of proteins. This family of proteins has been suggested to play an important role in innate anti-viral immunity. APOBEC3G is a cytidine deaminase enzyme which turns cytidine into uridine. APOBEC3G exerts innate antiretroviral immune activity against retroviruses most notably HIV by interfering with proper replication.
