IDENTIFICATION OF N-(4-PIPERIDINYL)-4-(2,6-DICHLOROBENZOYLAMINO)-1H-PYRAZOLE-3-CARBOXAMIDE (AT7519), A NOVEL CYCLIN DEPENDENT KINASE INHIBITOR USING FRAGMENT-BASED X-RAY CRYSTALLOGRAPHY AND STRUCTURE BASED DRUG DESIGN.

The structure was published by Wyatt, P.G., Woodhead, A.J., Berdini, V., et al., Trewartha, G., Walker, M.T., and Woolford, A.J., in 2008 in a paper entitled "Identification of N-(4-Piperidinyl)-4-(2,6-Dichlorobenzoylamino)-1H-Pyrazole-3-Carboxamide (at7519), a Novel Cyclin Dependent Kinase Inhibitor Using Fragment-Based X-Ray Crystallography and Structure Based Drug Design." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 2008.

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 274 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.
