The structure of cyclin-dependent kinase 2 (CDK2) in complex with 4-[(6-amino-4-pyrimidinyl)amino]benzenesulfonamide

The structure was published by Clare, P.M., Poorman, R.A., Kelley, L.C., Watenpaugh, K.D., Bannow, C.A., and Leach, K.L., in 2001 in a paper entitled "The cyclin-dependent kinases cdk2 and cdk5 act by a random, anticooperative kinetic mechanism" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.96 Å and deposited in 2001.

The experimental data on which the structure is based was not 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 287 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.
