The apolipoprotein mRNA editing enzyme catalytic polypeptide-like 3 (APOBEC3; A3) proteins are a family of seven cytidine deaminases (A3A, A3B, A3C, A3D, A3F, A3G and A3H) that restrict certain viral infections. These innate defence factors are best known for their ability to restrict the replication of human immunodeficiency virus type 1 (HIV-1) lacking a functional Vif protein (HIV-1?vif) through the deamination of cytidine residues to uridines during reverse transcription, ultimately leading to lethal G???A changes in the viral genome. The best studied of the A3 proteins has been APOBEC3G because of its potent activity against HIV-1?vif. However, one member of this family, A3A, has biological properties that make it unique among the A3 proteins. In this review, we will focus on the structural and phylogenetic features of the human and non-human primate A3A proteins, their role in the restriction of retroviruses and other viruses, and current findings on other biological properties affected by this protein.
