Chromosomal instability due to aberrant chromosome segregation is a hallmark of cancer, suggesting that a more detailed and mechanistic understanding of the molecular processes that control the faithful segregation of chromosomes will lead to new therapeutic strategies to control cancer. An example of this promise is evident in the Aurora kinases, which are important regulators of chromosome segregation. Several specific Aurora kinase inhibitors have demonstrated anti-proliferative activities and are proceeding to clinical trials even though we do not understand the multiple roles of this kinase. Our research involves the development of functional genomics approaches in baker's yeast, Saccharomyces cerevisiae, to focus on the kinase-signaling network of the yeast Aurora kinase, Ipl1. The downstream effects these phosphorylated substrates have on protein-protein interactions will be determined using an integrated approach relying on a phosphomutant scanning approach in conjunction with two-hybrid technology and systematic genetic studies. Identification of phosphomodulated genetic interactions and phosphomodulated protein-protein interactions related to Ipl1 and it's control of mitosis and chromosome segregation in yeast, should serve as a guide toward the analysis of and ultimately, intervention in, the abnormal mitotic pathways that propagate cancer cells.
