Current Research Interests:

Research in the Hall lab currently focuses on the regulation of mitosis by post-translational processes, including dynamic phosphorylation and ubiqutin-mediated protein degradation. One current project is studying mechanisms of anaphase-promoting complex function. The anaphase-promoting complex is a large E3 ubiquitin ligase that controls the metaphase-anaphase transition, mitotic exit, and G1 phases of the cell cycle among other things. It is the indirect target of existing cancer chemotherapies like taxol and an attractive target for development of new chemotherapies. Our primary interest is understanding how this enzyme is regulated and how it recognizes the correct substrates at the right time to promote their degradation. A second project focuses on characterizing the phosphatases responsible for completing mitosis and cytokinesis during the eukaryotic cell cycle. Much work has focused on understanding the kinases that control cell division but much less is known about their counteracting phosphatases. We are interested in understanding how multiple phosphatases with distinct specificities act together to coordinate mitotic exit and cytokinesis, and maintain genome stability.
