P27(KIP1)/CYCLIN A/CDK2 COMPLEX

Contents

Overview

The crystal structure of the human p27Kip1 kinase inhibitory domain bound, to the phosphorylated cyclin A-cyclin-dependent kinase 2 (Cdk2) complex, has been determined at 2.3 angstrom. p27Kip1 binds the complex as an, extended structure interacting with both cyclin A and Cdk2. On cyclin A, it binds in a groove formed by conserved cyclin box residues. On Cdk2, it, binds and rearranges the amino-terminal lobe and also inserts into the, catalytic cleft, mimicking ATP.

Disease

Known diseases associated with this structure: Multiple endocrine neoplasia, type IV OMIM:[600778]
