The ubiquitin proteasome system

Our group is studying the role of the ubiquitin-proteasome system (UPS) in the regulation of the mammalian cell cycle, DNA damage response, and apoptosis. We are particularly interested in how these mechansisms, when deregulated, contribute to the pathogenesis of hematologic malignancies. Our interdisciplinary approach ranges from biochemistry, proteomics and cell biology to mouse genetics.
