Structural Insights into a Unique Inhibitor Binding Pocket in Kinesin Spindle Protein
摘要:
Human kinesin Eg5 is a target for drug development in cancer chemotherapy with compounds in phase II clinical trials. These agents bind to a well-characterized allosteric pocket involving the loop L5 region, a structural element in kinesin-5 family members thought to provide inhibitor specificity. Using X-ray crystallography, kinetic, and biophysical methods, we have identified and characterized a distinct allosteric pocket in Eg5 able to bind inhibitors with nanomolar K-d. This pocket is formed by key structural elements thought to be pivotal for force generation in kinesins and may represent a novel site for therapeutic intervention in this increasingly well-validated drug target.
