== Function ==

[https://www.uniprot.org/uniprot/ABC3F_HUMAN ABC3F_HUMAN] DNA deaminase (cytidine deaminase) which acts as an inhibitor of retrovirus replication and retrotransposon mobility via deaminase-dependent and -independent mechanisms. Exhibits antiviral activity against vif-deficient HIV-1. After the penetration of retroviral nucleocapsids into target cells of infection and the initiation of reverse transcription, it can induce the conversion of cytosine to uracil in the minus-sense single-strand viral DNA, leading to G-to-A hypermutations in the subsequent plus-strand viral DNA. The resultant detrimental levels of mutations in the proviral genome, along with a deamination-independent mechanism that works prior to the proviral integration, together exert efficient antiretroviral effects in infected target cells. Selectively targets single-stranded DNA and does not deaminate double-stranded DNA or single- or double-stranded RNA. Exhibits antiviral activity also against hepatitis B virus (HBV), equine infectious anemia virus (EIAV), xenotropic MuLV-related virus (XMRV) and simian foamy virus (SFV) and may inhibit the mobility of LTR and non-LTR retrotransposons. May also play a role in the epigenetic regulation of gene expression through the process of active DNA demethylation.<ref>PMID:15152192</ref> <ref>PMID:16527742</ref> <ref>PMID:16378963</ref> <ref>PMID:19458006</ref> <ref>PMID:20219927</ref> <ref>PMID:20335265</ref> <ref>PMID:20062055</ref> <ref>PMID:21496894</ref> <ref>PMID:21835787</ref> <ref>PMID:22915799</ref> <ref>PMID:22807680</ref> <ref>PMID:23097438</ref> <ref>PMID:23152537</ref>
