Research Focus

Research Focus

Phosphorylation and proteolysis in cell cycle control, cancer and neuorodegenerative disorders.

Research in our laboratory focuses on the molecular basis for regulation of cell cycle progression and how proteins that normally regulate cell proliferation contribute to carcinogenesis when they become dysregulated. Our investigations center around a family of conserved enzymes known as cyclin-dependent kinases (and proteins that regulate them), which have been shown to be central to control of cell division in all eukaryotic organisms. For these studies we use model systems ranging from yeast, to mice to human cells in culture and methodologies ranging from genetic analysis, to cytological analysis and biochemistry. Much of our recent work has focused on the role of regulated proteolysis in cell cycle control and how defects in the proteolytic machinery can promote carcinogenesis, as well neurodegenerative disease.  We are using this information to develop novel therapeutic strategies.
