The Src tyrosine kinase is the paradigm of an oncogenic kinase, and of regulation by intramolecular inhibitory interactions, as well as an important anticancer target due to its roles in cell proliferation and metastasis. The assignment of backbone 1HN, 13Cα, 13CO, and 15N, and sidechain 13Cβ resonances of the catalytic domain of Src (283 residues) in complex with the anticancer drug Imatinib is reported here. Consistent with previous X-ray studies of the same complex, most signals from the activation loop are not detected, indicating that, even in the presence of the drug, it probably adopts highly heterogeneous conformations in intermediate exchange. For the rest of the polypeptide backbone, assignments have been completed for ~88% of residues, with only a few solvent-exposed amides remaining unassigned.
