Cyclin-dependent kinase 1 (CDK1)

Cyclin-dependent kinase 1 (CDK1) is an essential enzyme that plays a key role in cell division. It acts like a molecular switch, helping cells progress through the critical phases of dividing and replicating. CDK1 pairs with regulatory proteins called cyclins, which activate it at the right time. This activation triggers the cell’s machinery to prepare for division, ensuring new cells form correctly. Proper functioning of CDK1 is vital for growth, development, and tissue repair. Its activity is tightly controlled, and errors can lead to issues like uncontrolled cell growth, which is associated with cancer.
