Abstract: | How host–virus co‐evolutionary relationships manifest is one of the most intriguing issues in virology. To address this topic, the mammal–lentivirus relationship can be considered as an interplay of cellular and viral proteins, particularly apolipoprotein B mRNA editing enzyme catalytic polypeptide‐like 3 (APOBEC3) and viral infectivity factor (Vif). APOBEC3s enzymatically restrict lentivirus replication, whereas Vif antagonizes the host anti‐viral action mediated by APOBEC3. In this study, the focus was on the interplay between feline APOBEC3 proteins and two feline immunodeficiency viruses in cats and pumas. To our knowledge, this study provides the first evidence of non‐primate lentiviral Vif being incapable of counteracting a natural host's anti‐viral activity mediated via APOBEC3 protein. |
