WebOct 24, 2024 · Cyclins are known to bind to and activate proteins called cyclin-dependent kinases (CDKs), which are responsible for orchestrating the events of the cell cycle. This coordinated control of cell division is essential for ensuring that cells divide in a timely and controlled manner. WebCyclins and cyclin-dependent kinases (CDKs) are the fundamental regulators of the eukaryotic cell cycle. Through periodic synthesis and degradation of the cyclin partner, the CDK is sequentially activated and inactivated (Johnson and Walker, 1999).
