  1. The Dynamic Interplay Between Lentiviral Vif and Human APOBEC3 Proteins

    Wang, Jiayi2019

    … HIV-1 counteracts restriction with its Vif protein, which nucleates a ubiquitin ligase complex that directly binds A3 enzymes and targets them for proteasomal degradation. My thesis research aims at understanding the dynamic interplay between lentiviral Vif and human A3 enzymes, from the …
