Development of high-throughput screens for discovery of kinesin adenosine triphosphatase modulators.

Kinesins are a group of related molecular motor proteins that have great potential as targets for antimitotic drug development. We have developed two novel assays, one end-point and one kinetic, that are useful for the discovery and optimization of kinesin modulators. Both assays measure inorganic phosphate (Pi) generated by microtubule-activated kinesin adenosine triphosphatase activity.
