Cyclins are regulatory subunits of protein kinases.
Explanation:
- Cyclin subunits are essential for activation of the protein kinase activity.
- The levels of cyclins fluctuate during the cell cycle and in response to cellular and extracellular signals.
- Hence, results in changes in the activities of the cyclin-dependent protein kinases that in turn regulate and control the cell cycle.
