1 Cdc2 is likely to be inhibited by Thr-14/Tyr-15 phosphorylation after irradiation because Cdc2 was tyrosine-phosphorylated, and recombinant Cdc25 was able to increase its kinase activity significantly. Threonine cyclin dependent kinase 1 Homo sapiens

3 Taken together, these results suggest that different CDKs are inhibited by different mechanisms following UV-induced DNA damage: Cdk2 is inhibited by the elevated level of p21; Cdk4 is inhibited by cooperation of p21 with other CDK inhibitors, like p27, and possibly by phosphorylation; and Cdc2 is inhibited by Thr-14/Tyr-15 phosphorylation. Threonine cyclin dependent kinase 1 Homo sapiens
