CDC2/CDK1 Small Molecules and Peptides

CDC2 (Cell Division Cycle 2), also known as CDK1 (Cyclin Dependent Kinase 1), is a member of the CDK family of serine/threonine kinases. The CDKs are important regulators of cell cycle progression and their activities are largely controlled by association with Cyclins, and activating and inhibitory phosphorylations. Entry into mitosis is initiated by CDC2. Full activation of CDC2 requires phosphorylation at T161 and association with CyclinB. In contrast, phosphorylation of CDC2 at Y15 and T14 during the G2-phase of the cell cycle inhibits activity, and dephosphorylation of Y15 and T14 by CDC25 phosphatase during late G2 restores activity.
