WebDec 23, 2024 · Cyclin-dependent kinases (CDKs) are key players in cell cycle regulation. So far, more than ten CDKs have been described. Their direct interaction with cyclins allow progression through G1 phase, transitions to S and G2 phase and finally through mitosis (M). While CDK activation is important in cell renewal, its aberrant expression can lead … WebActive cyclin-CDK complexes activate Cdc25 and inactivate Wee1. Increased Cdc25 activity and decreased Wee1 activity generate large amounts of active cyclin-CDK. The positive feedback loop creates a switch-like change in cyclin-CDK activity in which cyclin-CDK activity is converted from low to high very quickly.
