text: Sarah first demonstrated that myosin-10 localizes to mitotic spindles in Xenopus embryonic epithelial cells (Spindle figure 4) and then went on to show that if it is knocked down (ie if the levels of myosin-10 protein are reduced), a variety of severe phenotypes result: the spindles lengthen, they develop extra poles, they display slower-than-normal movement, and they take far longer than normal to transit through mitosis (see the paper published in the Journal of Cell Biology: http://jcb.rupress.org/content/182/1/77.long).
