Assays for the detection of microtubule depolymerization inhibitors

摘要

This invention provides assays for agents that modulate (e.g. upregulate, downregulate or completely inhibit) microtubule depolymerizing or microtubule severing proteins. Such agents will have profound effects on progression of the cell cycle and act as potent anti-mitotic agents. The microtubule severing protein or microtubule depolymerizing protein is preferably a katanin, a p60 subunit of a katanin, an XKCM 1, or an OP18 polypeptide.
