Cyclin-dependent kinases (CDKs)
Cyclin-dependent kinases (CDKs) are crucial proteins in the cell that help regulate the cell cycle, which is the process of cell division and growth. They act like molecular "switches," activating or deactivating other proteins by adding a phosphate group in a process called phosphorylation. CDKs work in tandem with proteins called cyclins, which determine when CDKs are active. This partnership ensures that cells progress through different phases in a controlled manner, ensuring proper division and function, which is vital for overall health and development. Disruptions in CDK activity can lead to diseases, including cancer.

Cyclin-dependent kinases (CDKs) are important proteins in cells that help regulate the cell cycle, which is the process of cell division and growth. They act like molecular switches that control when a cell moves from one phase of the cycle to another. CDKs require specific partners called cyclins to function, and their activity is tightly regulated to ensure cells divide correctly. This regulation is crucial for proper development and maintaining health; malfunctioning CDKs can lead to issues like cancer, where cells divide uncontrollably. Thus, CDKs play a key role in the life cycle of cells.
