Epstein-Barr virus (EBV) is herpesvirus that infects most people and is maintained for life due to interplay between latent and lytic modes of infection. While often asymptomatic, EBV can cause several cancers due to its ability to efficiently immortalize cells. EBV encodes ~80 proteins, many of which are uncharacterized but thought to function to manipulate cellular processes, including cell cycle progress, DNA damage responses and ubiquitin and SUMO modification pathways. My lab is determining the roles of EBV proteins in host cell manipulation as well as identifying cellular factors that restrict and regulate EBV infection.
