Reactivity Key:  H=Human  R=Rat
Species cross-reactivity is determined by Western blot.

Specificity / Sensitivity

CDK7 (MO1) Mouse mAb detects endogenous levels of total CDK7 protein. The antibody does not cross-react with other CDKs.

Source / Purification

Monoclonal antibody is produced by immunizing mice with recombinant human CDK7.

Western Blotting

Western Blotting

Immunocytochemical analysis of HeLa cells, showing nuclear localization, using CDK7 (MO1) Mouse mAb.


Background

CDK-activating kinase (CAK) is a complex of CDK7 and cyclin H. The complex is involved in cell cycle regulation by phosphorylating an activating residue in the T-loop domain of cdks (1). Regulation of CAK activity is mediated by T-loop phosphorylation and by association with MAT1, both of which enhance its kinase activity toward the CTD of RNA polymerase II (2,3) and other substrates such as p53 (4). CAK is an essential component of the transcription complex TFIIH and may interact directly with TFIIH helicases (5).
