The kinesin-like spindle protein Eg5 (also known as kinesin-5, kinesin family protein 11, or Kif11) is a motor protein that is essential for establishing a bipolar spindle during mitosis both in normal and tumor cells. Ispinesib is a cell-permeable, allosteric inhibitor of Eg5 (Ki app = 2.3 nM) with >10,000-fold...
