Rapid evolution of primate antiviral enzyme APOBEC3G.

Abstract excerpt

Human cytidine deaminase APOBEC3G and the virion infectivity factor (vif) of the human immunodeficiency virus (HIV) are a pair of antagonistic molecules. In the absence of vif, APOBEC3G induces a high rate of dC to dU mutations in the nascent reverse transcripts of HIV that leads to the degradation of the HIV genome. HIV vif, on the other hand, can suppress the translation and trigger the degradation of human...
