HUMAN CYCLIN-DEPENDENT KINASE 2

The structure was published by Schulze-Gahmen, U., De Bondt, H.L., and Kim, S.H., in 1996 in a paper entitled "High-resolution crystal structures of human cyclin-dependent kinase 2 with and without ATP: bound waters and natural ligand as guides for inhibitor design." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 1996.

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

The PDB entry contains the structure of HUMAN CYCLIN-DEPENDENT 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 294 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
