  The macromolecular complex Mediator plays important roles in regulation of RNA Polymerase II (RNAPII) activity by DNA-binding proteins, non-coding RNAs, and chromatin. Structural and biochemical studies have shown that human Mediator exists in two forms; a core complex of 26 proteins, termed Mediator, and a larger complex containing the CDK8 kinase module, termed CDK8-Mediator. Interestingly, 3 subunits of the kinase module have undergone independent gene duplications in vertebrates to generate the paralog pairs MED12/MED12L, MED13/ MED13L, and CDK8/CDK19. Each has been shown to interact with Mediator, yet clearly defining the composition of CDK kinase module has been challenging due to the large size (~600 kD), the similarities between paralogs, and potential combinatorial nature of complexes. In this study, we performed a systematic proteomic analysis using HaloTag technology t.. View More»
