Abstact

The crystal structure of the human cyclinA-cyclin-dependent kinase2 (CDK2)-ATP complex has been determined at 2.3 A resolution. CyclinA binds to one side of CDK2's catalytic cleft, inducing large conformational changes in its PSTAIRE helix and T-loop. These changes activate the kinase by realigning active site residues and relieving the steric blockade at the entrance of the catalytic cleft.
