Phosphorylation of the ATP-binding loop directs oncogenicity of drug-resistant BCR-ABL mutants.

The success of targeting kinases in cancer with small molecule inhibitors has been tempered by the emergence of drug-resistant kinase domain mutations. In patients with chronic myeloid leukemia treated with ABL inhibitors, BCR-ABL kinase domain mutations are the principal mechanism of relapse. Certain mutations are occasionally detected before treatment… CONTINUE READING
