          Product Specific Information

          The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE).

          Target Information

          CDK8 phosphorylates the carboxy-terminal domain of the largest subunit of RNA polymerase II. This protein is coexpressed and copurified with Cyclin C. CDK8 is part of a family of proteins designated as cdks are critical regulators of cell cycle progression. The prototype member of this family, p34/Cdc 2, and a related protein Cdk 2, function late in the cycle while Cdk 4 and Cdk 6 are critically involved in G1 to S progression. Because of analogy with yeast Cdk 8, it has been proposed that the human Cdk 8 Cyclin C may interact with RNA polymerase, thus influencing the transcription mechanism(s) that lead to cell division.
