METHODS FOR IDENTIFYING MODULATORS OF KINESIN ACTIVITY

摘要

In a first aspect, the invention provides methods for screening for modulato rs of a target protein, comprising the steps of contacting a target protein wit h a candidate agent and determining whether the candidate agent modulates the activity of the target protein, wherein the target protein comprises a sequence that has more than 80% amino acid sequence identity to KIF14 (SEQ I D NO:2) or the KIF14 motor domain (SEQ ID NO:3). In a second aspect, the invention provides methods for modulating cell proliferation comprising administering to a cell an effective amount of a modulator of the activity o f a target protein. Some embodiments of this aspect provide methods for treati ng a subject with a cellular hyperproliferation disorder, such as cancer. In a third aspect, the invention provides methods for identifying candidate subjects for treatment with an inhibitor of the activity of a target protein .
