About
Accurate chromosome segregation during mitosis is necessary to prevent genetic instability and aneuploidy that are associated with cancer and many types of birth defects. Central to nearly all mitotic events are kinetochores, which are large proteinaceous structures located at the primary constriction, or centromere region, of mitotic chromosomes. Kinetochores are the sites where microtubules of the mitotic spindle attach to chromosomes, and they are responsible for producing force at this attachment site for chromosome movements during mitosis. Kinetochores also function to monitor these attachments and activate a cell-cycle checkpoint which inhibits anaphase onset until all chromosomes are properly bi-oriented and aligned at the metaphase plate. Research in our lab focuses on understanding how the vertebrate kinetochore accomplishes these remarkable tasks during mitosis using a combination of cell biological, biochemical, and proteomic approaches.
