1unh Summary



The structure was published by Mapelli, M., Massimilinao, L., Crovace, C., et al., Tsai, L.-H., Meijer, L., and Musacchio, A., in 2005 in a paper entitled "Mechanism of Cdk5/P25 Binding by Cdk Inhibitors" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.35 Å and deposited in 2003.

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