CDK2/CYCLIN A IN COMPLEX WITH AN 11-RESIDUE RECRUITMENT PEPTIDE FROM P107

The structure was published by Lowe, E.D., Tews, I., Cheng, K.Y., et al., Noble, M.E.M., Gamblin, S., and Johnson, L.N., in 2002 in a paper entitled "Specificity Determinants of Recruitment Peptides Bound to Phospho-Cdk2/Cyclin A" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.8 Å and deposited in 2002.

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

This PDB entry contains a complex of 3 biomacromolecules, namely CELL DIVISION PROTEIN KINASE 2, CYCLIN A2, and RETINOBLASTOMA-LIKE PROTEIN 1.

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