General description

Cell division protein kinase 7 is an enzymes encoded by the CDK7 gene in humans. The protein belongs to cyclin-dependent protein kinase (CDK) family. CAK is a CDK-cyclin complex implicated in the control of multiple cell cycle transitions. The structure of CDK7 facilitates the inhibitors with differential specificity for the different CDKs and can be used in different biological processes.


The antibody reacts specifically with Cdk7 (40 kDa catalytic subunit of Cdk activating kinase).


Monoclonal Anti-Cdk7/CAK antibody produced in mouse is suitable for the following applications:
• Immunocytochemistry
• Immunohistochemistry (frozen sections)
• Immunoprecipitation
• Microarray
• Western blotting at a dilution of 1:50,000 using a cultured human cell line extract

Biochem/physiol Actions

Cyclin-dependent kinase (CDK) Activating Kinase (CAK) is involved in activation and phosphorylation of CDK1, CDK2, CDK4 and CDK6 and regulation of the cell cycle. It is required for cell cycle progression and it could be a target for cancer therapy. CAK plays a central role in regulation of messenger RNA synthesis by either inhibition of RNA polymerase II-catalyzed transcription or stimulation of transcription through association with basal transcription repair factor IIH. Phosphorylation by the CDK-activating kinase (CAK) is required for the activation of cyclin-dependent kinases.
