Protein Structure

Function |
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. {ECO:0000269PubMed:15152192, ECO:0000269PubMed:16378963, ECO:0000269PubMed:16527742, ECO:0000269PubMed:19458006, ECO:0000269PubMed:20062055, ECO:0000269PubMed:20219927, ECO:0000269PubMed:20335265, ECO:0000269PubMed:21496894, ECO:0000269PubMed:21835787, ECO:0000269PubMed:22807680, ECO:0000269PubMed:22915799, ECO:0000269PubMed:23097438, ECO:0000269PubMed:23152537}.
