My lab studies cell division in human cells, with particular focus on regulation by ubiquitin-mediated proteolysis. We use time-lapse fluorescence imaging of live cells to measure proteolysis of substrates in real time, and to study the role of substrate proteolysis in the precisely coordinated events giving rise to two daughter cells at the end of mitosis. The Aurora kinases (Aurora A and Aurora B) are two substrates of ubiquitin-mediated proteolysis that make critical contributions to coordinated cell division, and have well documented cancer-promoting activities. Ongoing projects in the lab explore how ubiquitination of Aurora kinases regulates their activity in time and space, and how their activity contributes to cancer. We have recently described a 'ubiquitome' of cellular components modified by ubiquitin at the end of mitosis, seeding new projects to investigate how and why ubiquitin targeting regulates different processes in cell division.
