摘要:
Described herein are methods of identifying compounds which modulate the activity of the cytoskeletal system. The methods are rapid, convenient and sensitive. Preferably, the method is used to identify lead compounds that can be used as therapeutics, diagnostics and agricultural agents. Generally, test compounds are added to two cytoskeletal components which bind to one another, to determine whether the binding is affected by the test compound. Wherein the binding is affected, a compound which modulates the cytoskeletal system is identified.

摘要:
The present invention features methods for purifying polypeptides of interest using a modified Fluorescein arsenical helix binder (FlAsH) compound immobilized on a solid support. An exemplary FlAsH target sequence motif is also presented. Examples of modification of the FlAsH compound which allow immobilization to a solid support are also provided. The present invention also provides DNA constructs for producing a dual affinity tagged polypeptide and methods for purification thereof.

This invention provides methods for the screening and identification of agents having potent effects on the progression of the cell cycle. In one embodiment, the methods involve contacting a polymerized microtubule with a microtubule severing protein or a microtubule depolymerizing protein in the presence of an ATP or a GTP and a test agent; and (ii) detecting the formation of tubulin monomers, dimers or oligomers. The p60 subunit of katanin provides a particularly preferred microtubule severing protein possessing both ATPase and microtubule severing activities.
