CRYSTAL STRUCTURE OF CHK2 IN COMPLEX WITH AN INHIBITOR

The structure was published by Caldwell, J.J., Welsh, E.J., Matijssen, C., et al., Oliver, A.W., Garrett, M.D., and Collins, I., in 2011 in a paper entitled "Structure-Based Design of Potent and Selective 2-(Quinazolin-2-Yl)Phenol Inhibitors of Checkpoint Kinase 2." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 2010.

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

The PDB entry contains the structure of SERINE/THREONINE-PROTEIN KINASE CHK2.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms homodimers.
