How do cyclins and cdks work
WebSep 12, 2024 · The formation of cyclin/CDKs controls the cell-cycle progression via phosphorylation of the target genes, such as tumor suppressor protein retinoblastoma (Rb). The activation of cyclins/CDKs is induced by mitogenic signals and inhibited by the activation of cell-cycle checkpoints in response to DNA damage [8]. Table of Contentsshow WebWhat does the Cdk cyclin complex do? Functions of Cyclin-CDK in the Cell Cycle and Quiescence. Perhaps the most understood function of cyclins and CDKs is their control of cell cycle progression. Cyclin-CDK complexes appear to be the ‘master regulators’ of the cell cycle, controlling the events and timing that define each phase (Figure 4).
