Research Interests
In the Cavanaugh lab we use two related species of yeast, S. cerevisiae, and K. lactis, to study the organization, dynamics, and evolution of the spindle pole body (SPB). The SPB is a microtubule organizing center and serves to organize and regulate the formation of the mitotic spindle in yeast. Although the function of the SPB is vitally important for yeast reproduction, the structure and composition of this large, multi-protein structure varies widely across the yeast phyla. By studying the SPB in two species of budding yeast we hope to uncover mechanisms by which individual proteins are able to co-evolve as part of a large protein structure.
