| Abstract: | "The cyclin dependent kinases (CDKs), formed by complexes between Cdc2p and the B-cyclins Cig2p and Cdc13p, have a central role in regulating the fission yeast cell cycle and maintaining genomic stability. The CDK Cig2p/Cdc2p controls the onset of S-phase and the CDK Cdc13p/Cdc2p controls the onset of mitosis and ensures that there is only one S-phase in each cell. Cdc13p/Cdc2p can replace Cig2p/Cdc2p forthe onset of S-phase, suggesting that the increasing activity of a single CDK during the cell cycle is sufficient to drive a cell in an orderly fashion into S-phase and into mitosis. If S-phase is incomplete, then inhibition of Cdc13p/ Cdc2p prevents cells with unreplicated DNA from undergoing a catastrophic entry into mitosis. Control of CDK activity is also important to allow cells to exit the cell cycle and accumulate in G1 in response to nutritional deprivation and the presence of pheromone" |
