HUMAN CYCLIN DEPENDENT KINASE 2 COMPLEXED WITH THE INHIBITOR STAUROSPORINE

The structure was published by Lawrie, A.M., Noble, M.E., Tunnah, P., Brown, N.R., Johnson, L.N., and Endicott, J.A., in 1997 in a paper entitled "Protein kinase inhibition by staurosporine revealed in details of the molecular interaction with CDK2." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 1997.

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

The PDB entry contains the structure of CYCLIN-DEPENDENT 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 276 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.
