Cyclin-Dependent Kinases

Cyclin-dependent kinases (CDKs) are essential proteins in cells that help regulate the cell cycle, which is the process by which cells grow and divide. CDKs act like molecular switches, activated by proteins called cyclins. When they bind together, CDKs initiate various processes that allow a cell to transition from one phase of the cell cycle to another, ensuring proper growth and division. This coordination is vital for healthy development and function. Disruptions in CDK activity can lead to diseases, including cancer, highlighting their importance in maintaining cellular health.
