Cyclin-dependent kinase

Cyclin-dependent kinases (CDKs) are enzymes that control cell division and growth by regulating the cell cycle. They act as molecular switches, becoming active when paired with specific proteins called cyclins. Once activated, CDKs add phosphate groups to other proteins, triggering the progression of cells through different phases of division. This process ensures cells divide accurately and at the right time. Proper regulation of CDKs is crucial for healthy growth, and their malfunction can lead to diseases like cancer. In summary, CDKs are essential for coordinating cell growth and division through precise molecular control.
