Abstract/OtherAbstract:
Regulated interaction between kinetochores and the mitotic spindle is essential for the fidelity of chromosome segregation. Potentially deleterious attachments are corrected during prometaphase and metaphase. Correct attachments must persist during anaphase, when spindle-generated forces separate chromosomes to opposite poles. In yeast, the heterodecameric DASH complex plays a vital pole in maintaining this link. In vitro DASH forms both oligomeric patches and rings that can form load-bearing attachments with the tips of polymerising and depolymerising microtubules. In vivo, DASH localises primarily at the kinetochore, and has a role maintaining correct attachment between spindles and chromosomes in both Saccharomyces cerevisiae and Schizosaccharomyces pombe. Recent work has begun to describe how DASH acts alongside other components of the outer kinetochore to create a dynamic, regulated kinetochore-microtubule interface. Here, we review some of the key experiments into DASH function and discuss their implications for the nature of kinetochore-microtubule attachments in yeast and other organisms.
