General annotation (Comments)
| Function | DNA deaminase (cytidine deaminase) which acts as an inhibitor of retrovirus replication and retrotransposon mobility via deaminase-dependent and -independent mechanisms. Selectively targets single-stranded DNA and does not deaminate double-stranded DNA or single-or double-stranded RNA. Exhibits antiviral activity against HIV-1, simian immunodeficiency viruses (SIVs), mouse mammary tumor virus (MMTV) and friend murine leukemia virus (FrMLV) and may inhibit the mobility of LTR retrotransposons. Ref.6 Ref.8 Ref.9 Ref.11 |
| Catalytic activity | Cytidine + H2O = uridine + NH3. |
| Cofactor | Zinc By similarity. |
| Subunit structure | Homodimer. Interacts with mouse mammary tumor virus (MMTV) nucleocapsid protein p14. Ref.7 Ref.9 |
| Subcellular location | |
| Tissue specificity | Expressed in spleen, node and lung. Ref.5 |
| Domain | The CMP/dCMP deaminase zinc-binding 1 domain confers deoxycytidine deaminase activity, whereas the CMP/dCMP deaminase zinc-binding 2 domain mediates RNA-dependent oligomerization and virion incorporation (Ref.7). Ref.7 |
| Miscellaneous | Probable human APOBEC3G ortholog. |
| Sequence similarities | Belongs to the cytidine and deoxycytidylate deaminase family. Contains 2 CMP/dCMP deaminase zinc-binding domains. |

| Isoform 2 (identifier: Q99J72-2) The sequence of this isoform differs from the canonical sequence as follows: 409-429: SWGLQDLVNDFGNLQLGPPMS → VRTTLLQGPAS | ||||||
| Isoform 3 (identifier: Q99J72-3) The sequence of this isoform differs from the canonical sequence as follows: 198-230: Missing. 409-429: SWGLQDLVNDFGNLQLGPPMS → SRSHAS | ||||||
| Isoform 4 (identifier: Q99J72-4) The sequence of this isoform differs from the canonical sequence as follows: 198-230: Missing. | ||||||
| Note: Lacks exon V. Found in cell line MDTF. |
