What is the function of CDK?

Cyclin-dependent kinases (CDKs) are essential enzymes that regulate the cell cycle and other cellular processes by phosphorylating specific target proteins. They function in conjunction with cyclins, which activate CDKs at various checkpoints, ensuring proper progression through the different phases of the cell cycle. This regulation is crucial for maintaining cell division, growth, and overall cellular function. Dysregulation of CDKs can lead to various diseases, including cancer.
