Cdks are the catalytic subunits of serine/threonine protein kinases which are involved in the progression through the cell cycle. The catalytic activity of these kinases requires interaction with cyclins, which are synthesized and degraded during the cell cycle in a cyclical fashion. CDK2/CycE is important for the G1/S transition and initiating DNA replication. Additionally, CDK2/CycE phosphorylates proteins involved in Histone modifications (p220, CBP/p300) and DNA repair (BRCA1) and favours by phosphorylation the degradation of p27, an inhibitor of CDK2/CycE.
