CRYSTAL STRUCTURE OF CDK4 IN COMPLEX WITH A D-TYPE CYCLIN

The structure was published by Day, P.J., Cleasby, A., Tickle, I.J., et al., Chopra, R., Lengauer, C., and Jhoti, H., in 2009 in a paper entitled "Crystal Structure of Human Cdk4 in Complex with a D-Type Cyclin." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 2009.

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

This PDB entry contains a complex of 2 biomacromolecules, namely G1/S-SPECIFIC CYCLIN-D1 and CELL DIVISION PROTEIN KINASE 4.

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 most likely forms heterodimers.
