cyclin-dependent kinase

Abbreviation: CDK
A family of enzymes involved in regulation of the cell cycle. They serve as targets for pharmacological manipulation of this cycle, particularly during the unregulated proliferation of tumor cells.

The main components of RB pathway involves five family proteins; retinoblastoma tumor suppressor RB- family of pocket proteins (p110, p107, p130), E2F-family of transcription factors (heterodimers of E2F1-8 with DP1-2), cyclins (D and E-type), cyclin-dependent protein kinases (cdk4, cdk6) and cyclin-dependent kinase inhibitor CDKIs (p16Ink4a, p15Ink4b, p18Ink4c and p19Ink4d).

At day 1 after enucleation, 85 genes have been up-/downregulated, while at day 15 of the process only 7 such genes have been found, among them genes directly involved in cell cycle regulation, for example, cyclins (cyclin E1, E2, and B1), cyclin-dependent kinases (Cdk6 and Cdk1)--enzymes that regulate transcription, mRNA processing and progression of cell cycle, also enzymes involved in separation of sister chromatids during anaphase, centromere proteins (Cenpe and Cenpf), and kinetochore proteins (Ska3).
