Reaction: CAK-mediated phosphorylation of Cyclin A:Cdk2
- in pathway: Cyclin A:Cdk2-associated events at S phase entry
Phosphorylation of cyclin-dependent kinases (CDKs) by the CDK-activating kinase (CAK) is required for the activation of the CDK kinase activity. The association of p21/p27 with the Cyclin A/E:Cdk2 complex prevents CAK mediated phosphorylation of Cdk2 (Aprelikova et al., 1995).
