    • Function

      Component of the Mediator complex, a coactivator involved in regulated gene transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors. Phosphorylates the CTD (C-terminal domain) of the large subunit of RNA polymerase II (RNAp II), which may inhibit the formation of a transcription initiation complex. Phosphorylates CCNH leading to down-regulation of the TFIIH complex and transcriptional repression. Recruited through interaction with MAML1 to hyperphosphorylate the intracellular domain of NOTCH, leading to its degradation.

    • Immunoprecipitation of Cdk8 (3 µg of antibody per mg of HeLa cells lysate; 20% of the IP loaded). Lane 1- Immunoprecipitation with anti-Cdk8 antibody (ab115155); Lane 2-Immunoprecipitation with an anti-Cdk8 antibody that recognizes an upstream epitope; Lane 3- Immunoprecipitation with IgG control. An anti-Cdk8 antibody used in lane 2 was used at 0.4 µg/ml for western blot. Detection: Chemiluminescence with exposure time of 30 sec.
