     Current Research: My work in the Harris lab focuses on the human DNA cytosine deaminases APOBEC3F and APOBEC3G. Both of these proteins are able to block infection by human immunodeficiency virus type 1 (HIV-1) in the absence of the viral accessory protein virion infectivity factor (Vif). This restrictive activity does not typically manifest in vivo, however, because wild-type Vif-proficient viruses target APOBEC3F and APOBEC3G for degradation.

I am interested in the mechanisms by which APOBEC3F and APOBEC3G may block HIV-1 infection when no longer targeted by Vif. This work anticipates a future in which new classes of antiretroviral drugs will block the interaction of Vif with APOBEC3 proteins. In addition to this developing therapeutic scenario, I am also interested in the implications of APOBEC3 mutational activity for the efficacy of current antiretroviral therapies.
