Molecular forces are key to proper cell division

This shows the expression of the chromokinesin NOD (red) stabilizes aberrant interactions between kinetochores and spindle microtubules (green). Tension stabilizes bioriented attachments where each sister chromatid is attached to microtubules. Studies led by cell biologist Thomas Maresca at the University of Massachusetts Amherst are revealing new details about a molecular surveillance system that helps detect and correct errors in cell division that can lead to cell death or human diseases. Findings are reported in the current issue of the Journal of Cell Biology.
