Abstract

Cell-cycle transitions in higher eukaryotes are regulated by different cyclin-dependent kinases (CDKs) and their activating cyclin subunits. Based on pioneering findings that a dominant-negative mutation of CDK1 blocks the cell cycle at G2-M phase, whereas dominant-negative CDK2 inhibits the transition into S phase, a model of cell-cycle control has emerged in which each transition is regulated by a specific subset of CDKs and cyclins. Recent work with gene-targeted mice has led to a revision of this model. We discuss cell-cycle control in light of overlapping and essential functions of the different CDKs and cyclins.
