The effect of the interaction between apolipoprotein B mRNA editing enzyme-catalytic polypeptidelike 3G and viral infectivity factor on HIV-1 replication

Abstract

Apolipoprotein B mRNA editing enzyme-catalytic polypeptidelike 3G (APOBEC3G), which belongs to the APOBEC family, restricts the replication of HIV-1 through the deminase-dependent and deminase-independent antiviral mechanisms. Viral infectivity factor (Vif), an accessory protein edited by vif gene of HIV-1, promotes APOBEC3G ubiquitination and subsequent degradation by the proteasome result ing in the increased replication of HIV-1. Over the past few years, the discovery of some co-factors such as CBF-β, HDAC6 and MDM2 not only raises our awareness of the interaction between APOBEC3G and Vif but also provides new antiviral targets of HIV-1 in addition. Here we review the structure of APOBEC3G and Vif, and the effect of interference agents on HIV-1 replication by interacting with APOBEC3G and Vif. Key words: HIV-1; APOBEC3G; Vif
