Research Summary
My lab seeks to understand the eukaryotic cell cycle at a biochemical level. To get there, we use a variety of approaches ranging from genetics and “pseudo genetics” in yeast to biochemistry and enzyme assays using cell extracts and purified proteins from yeast and mammalian cells. We focus on two broad areas: Post-translational modification and activation of the cyclin-dependent kinases (CDKs) that control the cell cycle, and ubiquitin-dependent proteolysis of cyclins and other proteins by the Anaphase-Promoting Complex and how this proteolysis is controlled by cellular checkpoints. Progressing from genetic identification of components through their study in vitro we hope to achieve a more complete understanding of these macroscopic cellular behaviors.
