Abstract

We have used a chemically diverse panel of kinase inhibitors to assess the chemical similarity of the ATP-binding sites of cyclin-dependent kinase (CDK) subfamily members in a range of activation states. Using this approach, we find that different activation states of a particular CDK may differ from each other as much as different CDKs in the same activation state. We also find that inhibitors discriminate more effectively among CDK family members in their monomeric state than in their cyclin-bound state, providing direct evidence for the belief that selective binding to inactive kinase states might be more readily achieved than selective binding to active states.
