APOBEC-3G Deaminase

An APOBEC deaminase that functions as an inhibitor of RETROVIRIDAE replication and inhibits the mobility of RETROTRANSPOSONS via deaminase-dependent and independent mechanisms. It is selective for SINGLE-STRANDED DNA and does not deaminate double-stranded DNA or single or DOUBLE-STRANDED RNA. It exhibits potent antiviral activity against VIF PROTEIN deficient HIV-1 through the creation of hypermutations in the VIRAL DNA. It also has anti-viral activity against SIMIAN IMMUNODEFICIENCY VIRUSES and HEPATITIS B VIRUS.
