STRUCTURE OF HUMAN THR160-PHOSPHO CDK2-CYCLIN A COMPLEXED WITH A BISANILINOPYRIMIDINE INHIBITOR
Overview
Cyclin dependent kinases are a key family of kinases involved in cell, cycle regulation and are an attractive target for cancer chemotherapy. The, roles of four residues of the cyclin-dependent kinase active site in, inhibitor selectivity were investigated by producing cyclin-dependent, kinase 2 mutants bearing equivalent cyclin-dependent kinase 4 residues, namely F82H, L83V, H84D, and K89T. Assay of the mutants with a, cyclin-dependent kinase 4-selective bisanilinopyrimidine shows that the, K89T mutation is primarily responsible for the selectivity of this, compound. Use of the cyclin-dependent kinase 2-selective, 6-cyclohexylmethoxy-2-(4'-sulfamoylanilino)purine (NU6102) shows that K89T, has no role in the selectivity, while the remaining three mutations have a, cumulative influence. The results indicate that certain residues that are, not frequently considered in structure-aided kinase inhibitor design have, an important role to play.
