All living organisms must transmit genetic information through successive generations, and all six eukaryotic supergroups utilize a mitotic spindle to accomplish this task. The mitotic spindle is the cellular machinery responsible for chromosome segregation during mitosis, and it is comprised of hundreds of proteins. During evolution, eukaryotic cells have developed different mechanisms and different kinds of mitotic spindles to segregate the chromosomes (Drechsler and McAinsh, 2012). Regardless of the differences, the common characteristic of all these different mitotic spindles is the utilization of microtubules and kinesins, as all known eukaryotes studied to this date possess kinesins (Wickstead et al., 2010).The mitotic spindle is a bipolar array of microtubules of varied lengths that continuously grow and shrink. These highly dynamic microtubules are nucleated by centrosomes and contact the chromosomes in the centromeric region to facilitate chromosome attachment and segregation. Although chromosome movement is powered in part by changes in microtubule assembly (Shelden and Wadsworth, 1992), kinesins associated with microtubules and other spindle structures refine the movement of chromosomes in the spindle. Kinesins participate in chromosome attachment, influence microtubule dynamics and contribute to anaphase spindle elongation (reviewed in (Cross and McAinsh, 2014)). Thus, kinesins, in conjunction with dynamic microtubules, ensure the proper distribution of genetic material between the two daughter cells to avoid aneuploidy.
