CDK-2-Cyclin complex with indazole inhibitor 9 bound at its active site

The structure was published by Trujillo, J.I., Kiefer, J.R., Huang, W., et al., Christine, L., Compton, R., and Li, X., in 2009 in a paper entitled "2-(6-Phenyl-1H-indazol-3-yl)-1H-benzo[d]imidazoles: Design and synthesis of a potent and isoform selective PKC-zeta inhibitor." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.4 Å and deposited in 2008.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Cell division protein kinase 2 and Cyclin-A2.

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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
