WebCyclins complex with cyclin dependent kinases (CDKs) to control progression through the cell cycle. Upon binding, cyclins activate their CDK partners, which can then phosphorylate their protein targets. Cyclin-dependent kinase inhibitors bind to active cyclin-CDK complexes, effectively inhibiting their activity. Web16 de ago. de 2024 · Acting together with one more enzyme, CAK (cdk-activating kinase), they activate the cdk (Figure 9.4. 3 ). Figure 9.4. 3. Activation of mitotic cyclin/cdk complex Using the mitotic cyclin/cdk complex as an example, the cyclin (cdc13) and cdk (cdc2) come together to form an inactive complex. The cdk is then phosphorylated by wee1, a kinase.
