According to these data, we propose a model that, during the process of HIV-1 infection, MOV10 can interact with ElonginC and Cullin 5 to disturb the interaction of Vif with ElonginB, ElonginC, Culiin 5 or CBF-β and subsequently interfere with the assembly of Vif-CBF-β-Cullin 5-ElonginB-ElonginC complex which induces the ubiquitination of A3G. This evidence concerns the gene APOBEC3G and HIV-1 infection.
