Drug resistant cSrc kinase domain in complex with covalent inhibitor PD168393

The structure was published by Klueter, S., Simard, J.R., Rode, H.B., et al., Rabiller, M., van Otterlo, W.A.L., and Rauh, D., in 2010 in a paper entitled "Characterization of irreversible kinase inhibitors by directly detecting covalent bond formation: a tool for dissecting kinase drug resistance" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.48 Å and deposited in 2010.

The experimental data on which the structure is based was also deposited.
