GenomicsHog1 controls global reallocation of RNA Pol II upon osmotic shock
When challenged with osmotic shock, S. cerevisiae induces hundreds of genes, despite a global reduction in transcriptional capacity. The mechanisms that regulate this rapid reallocation of transcriptional resources are not known. Here we show that redistribution of RNA Pol II upon stress requires ...

GenomicsPol II and its associated epigenetic marks are present at pol III-transcribed non-coding RNA genes (I)
Epigenetic control is an important aspect of gene regulation. Despite detailed understanding of many examples, the transcription of non-coding RNA genes by RNA polymerase (pol) III is less well characterized. Here we profile the epigenetic features of pol III target genes throughout the human gen...

GenomicsRegulation of Mediator-dependent transcriptional activation of Pol II(G) through TFII
Pol II(G) is a novel form of RNA polymerase II that contains a tightly associated Gdown1 polypeptide. Whereas Pol II suffices for robust activator-dependent transcription in the absence of Mediator, Pol II(G) is highly dependent upon Mediator in a biochemically defined in vitro system. However, the ...

TranscriptomicsChIP-chip by array of yeast to determine genome-wide occupancy profiles for RNA polymerase (Pol) II, its phosphorylated forms, and transcription factors
To investigate the chromatin transcription cycle, we determined genome-wide occupancy profiles for RNA polymerase (Pol) II, its phosphorylated forms, and transcription factors in growing yeast. ChIP-chip was performed to identify the genomic binding locations for Rpb3, TFIIB, Tfg1, Kin28, Cet1, Spt4...

TranscriptomicsZFP-1(AF10)/DOT-1 Complex Opposes H2B Ubiquitination to Reduce Pol II Transcription
Inhibition of transcriptional elongation plays an important role in gene regulation in metazoans, including C. elegans, which lacks Negative Elongation Factor homologs. Here we combine genomic and biochemical approaches to dissect a novel role of C. elegans AF10 homolog, ZFP-1, in transcriptional c...

TranscriptomicsMitotic Transcriptional Clearance of Actively Engaged Pol II Through Transcriptional Elongation Control
Chromatin is highly condensed and transcriptionally repressed during mitosis. Although it is established that some general transcription factors are inactivated by phosphorylation at mitosis, many details of mitotic transcriptional repression and its underlying mechanisms are largely unknown. Here, ...

GenomicsGenome-wide mapping of RNA Pol II binding site (GM12878)
We report the results of chromatin immunoprecipitation following by high-thoughput sequencing (ChIP-Seq) using the GA II platform from Illumina for the human RNA Polymerase II in GM12878 cells. We have also generated a sequenced input DNA datasets for GM12878 cells. For data usage terms and condit...

TranscriptomicsThe RNA Pol II Elongation Factor Ell3 Marks Enhancers in ES Cells and Primes Future Gene Activation
Enhancers play a central role in precisely regulating the spatiotemporal expression of developmentally regulated genes. The molecular mechanisms and factors required for controlling the inactive or poised enhancers and their function in future gene activation remain elusive. Here, we have identified...

GenomicsTyrosine phosphorylation of RNA Polymerase II CTD is associated with antisense promoter transcription and active enhancers in mammalian cells
In mammals, the carboxy-terminal domain (CTD) of RNA polymerase (Pol) II consists of 52 conserved heptapeptide repeats containing the consensus sequence Tyr1-Ser2-Pro3-Thr4-Ser5-Pro6-Ser7. Post-translational modifications of the CTD coordinate the transcription cycle and various steps of mRNA matura...
