(Submitter supplied) Fcp1 is a protein phosphatase that facilitates transcription elongation and termination by dephosphorylating the C-terminal domain of RNA Polymerase II. Here, we report an unanticipated role in the repression of the oxidative stress induced genes. High-throughput genetic and gene expression profiling of FCP1 mutants uncovered a link to Skn7, a key transcription factor in the oxidative stress response pathways, as well as a link to the Mediator complex kinase subunit, Cdk8. more...

(Submitter supplied) Gene regulation by cytokine-activated STAT transcription factors requires serine phosphorylation within the transactivation domain (TAD). STAT1 and STAT3 TAD phosphorylation was reported to occur upon promoter binding by an unknown kinase. Here we show that the Mediator CDK8 module phosphorylates S727 of the STAT1 TAD in the interferon (IFN) signaling pathway as well as the TADs of other STATs. Microarray analysis reveals that CDK8-mediated STAT1 TAD phosphorylation positively or negatively regulates over 40% of IFN-gamma-responsive genes, and RNA polymerase II occupancy correlates with gene expression changes. more...

(Submitter supplied) The Mediator complex regulates gene transcription by linking basal transcriptional machinery with DNA-bound transcription factors. The activity of the Mediator complex is mainly controlled by a kinase submodule that is comprised of four proteins, including MED12. Although ubiquitously expressed, Mediator subunits can differentially regulate gene expression in a tissue-specific manner. Here, we report that MED12 is required for normal cardiac function such that mice with conditional cardiac-specific deletion of MED12 display progressive dilated cardiomyopathy. more...

(Submitter supplied) The Mediator kinase module regulates eukaryotic transcription by phosphorylating transcription-related targets and by modulating the association of Mediator and RNA Polymerase II. The activity of its catalytic core, cyclin-dependent kinase 8 (CDK8), is controlled by Cyclin C and MED12, with its deregulation contributing to numerous malignancies. Here, we combine in vitro biochemistry, crosslinking coupled to mass spectrometry and in vivo studies to describe the binding location of the N-terminal segment of MED12 on the CDK8/Cyclin C complex and to gain mechanistic insights into the activation of CDK8 by MED12. more...

(Submitter supplied) CDK8 is a key subunit of Mediator complex, a large multiprotein complex that is a fundamental part of the conserved eukaryotic transcriptional machinery. However, the biological functions of CDK8 in plant abiotic stress responses remain largely unexplored. Here, we demonstrated CDK8 as a critical regulator in the abscisic acid (ABA) signaling and drought response pathways in Arabidopsis. Compared to wild-type, cdk8 mutants showed reduced sensitivity to ABA, impaired stomatal apertures and hypersensitivity to drought stress. more...

(Submitter supplied) Mediator complex has been known as pivotal regulator of RNA polymerase II. Mediator complex has two CDK subunits in vertebrates, named CDK8 and CDK19. To elucidate functional difference between CDK8 and CDK19 in human cell, we employ siRNA mediate knockdown assay using HeLa S3 cell line. According to this assay these CDKs possess highly redundancy in HeLa S3 cell transcription regulation mechanism but in several genes, each CDK shows gene specific regulatory function.
