A3F, or Apolipoprotein B mRNA editing enzyme, catalytic polypeptide-like 3F, is a human gene encoded by APOBEC3F. It may also be known as: DNA dC->dU-editing enzyme APOBEC-3F; Apolipoprotein B mRNA-editing enzyme catalytic polypeptide-like 3F; DNA dC->dU-editing enzyme APOBEC-3F ; BK150C2.4.MRNA; KA6. The encoded protein is an enzyme with an amino acid length of 373 and a mass of 45.0 kDa. A3F is a member of the Cytidine and deoxycytidylate deaminase family. Homologs of this gene exist in other organisms, including: Rat.
