Human dCK C4S-S74E mutant in complex with UDP and the DI-43 inhibitor

The structure was published by Murphy, J.M., Armijo, A.L., Nomme, J., et al., Jung, M.E., Lavie, A., and Radu, C.G., in 2013 in a paper entitled "Development of new deoxycytidine kinase inhibitors and noninvasive in vivo evaluation using positron emission tomography." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.94 Å and deposited in 2013.

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