Biochem/physiol Actions

CDK7 gene is a member of the cyclin-dependent protein kinase family that is important regulators of cell cycle progression. CDK7 forms a trimeric complex with cyclin H and MAT1, which functions as a CDK-activating kinase (CAK). CDK7 is an essential component of the transcription factor TFIIH that is involved in transcription initiation and DNA repair. CDK7 is thought to serve as a direct link between the regulation of transcription and the cell cycle.

Cell division is controlled by cyclin-dependent kinases (CDKs). In metazoans, S phase onset coincides with activation of Cdk2, whereas Cdk1 triggers mitosis. Both Cdk1 and -2 require cyclin binding and T loop phosphorylation for full activity. The only known CDK-activating

Cell, 78(4), 713-724 (1994-08-26)
Phosphorylation by the CDK-activating kinase (CAK) is a required step in the activation of cyclin-dependent kinases. We have purified CAK from mammalian cells; the enzyme comprises two major polypeptides of 42 and 37 kDa. Protein sequencing indicates that the 42
