    The solution structure of the tumor suppressor p16INK4A has been determined by NMR, and important recognition regions of both cdk4 and p16INK4A have been identified. The tertiary structure of p16INK4A contains four helix-turn-helix motifs linked by three loops. Twelve tumorigenic mutants of p16INK4A have been constructed and analyzed for their structure and activity, and new mutants have been designed rationally. A fragment of 58 residues at the N terminus of cdk4 important for p16INK4A binding has been identified. The importance of this region was further verified by mutational analysis of cdk4. These results and docking experiments have been used to assess possible modes of binding between p16INK4A and cdk4.
