Human cyclin dependent kinase 2 (CDK2) complexed with DPH-042562

The structure was published by Yue, E.W., Dimeo, S.V., Higley, C.A., et al., Chang, C.-H., Trainor, G.L., and Seitz, S.P., in 2004 in a paper entitled "Synthesis and Evaluation of Indenopyrazoles as Cyclin-Dependent Kinase Inhibitors. Part 4: Heterocycles at C3" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.88 Å and deposited in 2005.

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 283 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.
