Research Interests

Our research mainly focuses on the molecular mechanisms underlying virus-host interactions. Specifically, we identify new host factors that participate in the regulation of virus replication, and explore the underlying mechanisms. We used to work on the Zinc-finger Antiviral Protein (ZAP), which specifically binds to viral mRNA, represses its translation and recruits RNA degradation machinery to degrade the RNA. We recently identified a host antiviral factor, Shiftless, which inhibits programmed -1 ribosomal frameshifting. Shiftless inhibits the frameshiftling process of not only viral RNAs also cellular mRNAs. These results were published in high-profile journals such asScience,Cell,Cell Host & Microbe,EMBO JandPNAS. Our research in the near future will focus on two aspects: (1) identification and mechanistic analyses of novel host factors involved in HIV, SARS-CoV-2 replication (2) identification of cellular mRNAs that contain -1PRF signals and analyses of their functions in vivo using Shiftless knockout mice as a tool.
