1VYJ, 1VYM, 1W60 - PubMed Abstract: 
The interactions between the tumor suppressor protein p21WAF1 and the cyclin-dependent kinase (CDK) complexes and with proliferating cell nuclear antigen (PCNA) regulate and coordinate the processes of cell-cycle progression and DNA replication. We present the x-ray crystal structure of PCNA complexed with a 16-mer peptide related to p21 that binds with a Kd of 100 nM ...
