We have examined the activity of cyclin-dependent kinase 3 (cdk3) during G1-phase of the cell cycle in Chinese Hamster
Ovary
(CHO) fibroblasts. Histone H1 kinase activity associated with anti-cdk3 immunoprecipitates peaked during a brief window of time, 2-3 h prior to the restriction point. In vitro cdk3 activity was sensitive to roscovitine, a drug previously shown to inhibit cdks 1, 2, and 5, but not
cdk4
or 6. Early G1-phase activation of cdk3 was downregulated by treatment of cells with MG132, an inhibitor of the proteasome, and by the protein synthesis inhibitor cycloheximide. These results provide evidence for a pre-restriction point cdk3 activity that requires both the synthesis of a regulatory subunit and degradation of an inhibitor.
