Research Interests

The focus of our research is to understand the molecular mechanisms underlying protein degradation mediated by the ubiquitin-proteasome system (UPS). UPS is the primary intracellular machine responsible for elimination of abnormal proteins and selective destruction of regulatory proteins involved in a wide range of cellular processes including cell cycle control, DNA transcription, replication and repair, and stress response. Dys-regulation of UPS is implicated in various human diseases including cancers. Moreover, UPS has now become an important target for anti-cancer therapy. We use both Saccharomyces cerevisiae and mammalian systems to define the pathways that control the degradation of several key regulatory proteins. In addition, we are studying the differential response of normal cells and cancer cells to the inhibitors of UPS.
