Abstract
Deregulated CDK activity drives cell proliferation of the majority of human tumors, making CDKs highly relevant research subjects. Cdc28 controls cell cycle progression in the budding yeast Saccharomyces cerevisiae, but the identity of many genes that function in conjunction with CDC28 to regulate the cell cycle and cell viability remains obscure. In a recent study, we used a chemical-genetic screen to identify the genetic network of CDC28. Through this analysis, we discovered that the Rad6-Bre1 pathway functions in this network and links ubiquitin levels to cell cycle progression by increasing transcription of cyclin genes. Thus, Rad6 boosts the activity of the cell cycle machinery.
