Research Description

The goals of my laboratory are two-fold: 1) to understand the molecular mechanisms driving cytokinesis and 2) to learn how cytokinesis is coordinated with other events of mitosis including chromosome segregation. We are asking a) what is the nano-architecture of a contractile ring and what determines it, b) how is the cytokinetic machinery precisely localized between segregating chromosomes and anchored to the plasma membrane, c) what molecular signal triggers constriction of the acto-myosin machinery, and d) what ensures the correct timing of cytokinesis with respect to chromosome segregation?

To address these questions expeditiously, we use primarily yeast as a model organism. Using super-resolution imaging, proteomics, live cell imaging, genetics, biochemistry, and structural biology we are unraveling the sequence of events that directs formation and then constriction of the cytokinetic ring. We also study protein phosphorylation-based signaling pathways and ubiquitin ligases that control the spatial and temporal precision of cytokinesis in both yeast and mammalian cells.
