CDK2/CYCLIN A IN COMPLEX WITH AN 11-RESIDUE RECRUITMENT PEPTIDE FROM P27
OverviewOverview
Progression through S phase of the eukaryotic cell cycle is regulated by, the action of the cyclin dependent protein kinase 2 (CDK2) in association, with cyclin A. CDK2/cyclin A phosphorylates numerous substrates. Substrate, specificity often employs a dual recognition strategy in which the, sequence flanking the phospho-acceptor site (Ser.Pro.X.Arg/Lys) is, recognized by CDK2, while the cyclin A component of the complex contains a, hydrophobic site that binds Arg/Lys.X.Leu ("RXL" or "KXL") substrate, recruitment motifs. To determine additional sequence specificity motifs, around the RXL sequence, we have performed X-ray crystallographic studies, at 2.3 A resolution and isothermal calorimetry measurements on complexes, of phospho-CDK2/cyclin A with a recruitment peptide derived from E2F1 ...
