Cyclin dependent kinase 7 (complex with cyclin H)

Synonyms: CAK, CAK1, CDKN7, MO15, STK1

Family: CMGC

CDK7 is a serine/threonine protein kinase and a member of cyclin dependent kinase family. CDK7 forms the CDK-activating kinase (CAK) with cyclin H and MAT11. CAK activates downstream cell cycle CDKs, making CDK7 important regulator in cell cycle progression. CDK7 also phosphorylates serines in the carboxy-terminal domain of POLR2A, an essential step for efficient transcription2.

CDK7-CYCLIN H kinase assay is run on mobility shift microfluidics platform (Caliper), which provides best in industry quality of data. We routinely run services associated with this kinase including: screening, profiling, dose-response studies and kinetic measurements. Please contact us for more information.
