+== Publication Abstract from PubMed ==
+The cancer drug imatinib inhibits the tyrosine kinases c-Abl, c-Kit, and the PDGF receptor. Imatinib is less effective against c-Src, which is difficult to understand because residues interacting with imatinib in crystal structures of Abl and c-Kit are conserved in c-Src. The crystal structure of the c-Src kinase domain in complex with imatinib closely resembles that of Abl*imatinib and c-Kit*imatinib, and differs significantly from the inactive "Src/CDK" conformation of the Src family kinases. Attempts to increase the affinity of c-Src for imatinib by swapping residues with the corresponding residues in Abl have not been successful, suggesting that the thermodynamic penalty for adoption of the imatinib-binding conformation by c-Src is distributed over a broad region of the structure. Two mutations that are expected to destabilize the inactive Src/CDK conformation increase drug sensitivity 15-fold, suggesting that the free-energy balance between different inactive states is a key to imatinib binding.
