WebAug 16, 2007 · Unicellular organisms such as yeasts require a single cyclin-dependent kinase, Cdk1, to drive cell division. In contrast, mammalian cells are thought to require the sequential activation of at least four different cyclin-dependent kinases, Cdk2, Cdk3, Cdk4 and Cdk6, to drive cells through interphase, as well as Cdk1 to proceed through mitosis. WebRad53/Chk2, redundantly block mitotic Cyclin Dependent Kinase (M-Cdk1). Cdk1 is the engine that drives cell cycle progression, and M-Cdk1 is essential for cells to enter anaphase. Our results unveil an unsuspected implication of Rad53 in the control of Cdk1 activity, and reconcile the long-standing conundrum of Swe1 dispensability.

Given its essential role in cell cycle progression, Cdk1 is highly regulated. Most obviously, Cdk1 is regulated by its binding with its cyclin partners. Cyclin binding alters access to the active site of Cdk1, allowing for Cdk1 activity; furthermore, cyclins impart specificity to Cdk1 activity. At least some cyclins contain a hydrophobic patch which may directly interact with substrates, conferring target specificity. Furthermore, cyclins can target Cdk1 to particular subcellular locations.
