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. Induced by mitogenic signals cyclins of the D-type family (D1, D2, and D3) are synthesized and bind and activate CDK4 and CDK6. Active complexes are involved in entering the G1 phase and regulate the early phase of G1 by phosphorylation of the retinoblastoma protein (Rb), p107 and p130. The cyclin D1 gene is amplified and/or overexpressed in various human cancers. For this reason, cyclin-CDK complexes have been considered as very promising therapeutic targets in human malignancies.
