Crystal structure of CDK2 with SAR57, an aminoindazole type inhibitor

The structure was published by Lesuisse, D., Dutruc-Rosset, G., Tiraboschi, G., et al., Burgevin, M.C., Quarteronet, D., and Rooney, T., in 2010 in a paper entitled "Rational design of potent GSK3beta inhibitors with selectivity for Cdk1 and Cdk2." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.28 Å and deposited in 2010.

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

The PDB entry contains the structure of Cell division protein kinase 2. This molecule has the UniProt identifier P24941 (CDK2_HUMAN)search. The sample contained 298 residues which is 100% of the natural sequence. Out of 298 residues 285 were observed and are deposited in the PDB.

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 is most likely monomeric.
