Role of the mitotic cyclin Clb2 in mitotic regulation
... In the budding yeast Saccharomyces cerevisiae, the mitotic cell cycle is regulated by the cyclin-dependent kinase (CDK) Cdc28. Cdc28 is activated by binding to one of nine cyclins, which then directs Cdc28’s function and localization. Clb2 is the main mitotic cyclin, promoting entry into mitosis and ...
