GenomicsRNA polymerase II pausing downstream of core histone genes is different from genes producing polyadenylated transcripts
Recent genome-wide chromatin immunoprecipitation coupled high throughput sequencing (ChIP-seq) analyses performed in various eukaryotic organisms, analysed RNA Polymerase II (Pol II) pausing around the transcription start sites of genes. In this study we have further investigated genome-wide binding...

GenomicsRegulation of Mammalian Cell Growth and Survival By an RNA Polymerase II-Pausing Factor (ChIP-seq)
Many mammalian genes are occupied by paused RNA polymerase II (pol II) at promoter-proximal regions on both sides of transcription start sites (TSSs). However, the consequences of pol II pausing on gene expression and cell biology are not fully understood. Here we report that genetic ablation of t...

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...

GenomicsFunctional association of Gdown1 with RNA Polymerase II in Human
Most human genes are loaded with promoter proximally paused RNA polymerase II (RNAP II) molecules that are poised for release into productive elongation by P-TEFb. Gdown1, a protein that renders RNAP II responsive to mediator, is involved in RNAP II elongation control. During in vitro transcription ...

GenomicsPol II (Rpb3) ChIP-seq in Drosophila melanogaster S2 cells
Control of RNA transcription is critical for the development and homeostasis of all organisms, and can occur at multiple steps of the transcription cycle, including RNA polymerase II (Pol II) recruitment, initiation, promoter-proximal pausing, and elongation. That Pol II accumulates on many promoter...

GenomicsPol II chromatin immunoprecipitation in S. cerevisiae
In Saccharomyces cerevisiae short non-coding RNA (ncRNA) generated by RNA Polymerase II (Pol II) are terminated by the NRD complex consisting of Nrd1, Nab3 and Sen1. We now show that Pcf11, a component of the cleavage and polyadenylation complex (CPAC), is generally required for NRD-dependent transc...

TranscriptomicsGenome-wide control of RNA polymerase II activity by cohesin (sequencing)
Cohesin is a well-known mediator of sister chromatid cohesion, but it also influences gene expression and development. These non-canonical roles of cohesin are not well understood, but are vital: gene expression and development are altered by modest changes in cohesin function that do not disrupt ch...

GenomicsGenome-wide assay of Vezf1 and RNA Polymerase II binding
The protein Vezf1 plays multiple roles important for embryonic development. In Vezf1-/- mouse embryonic stem (MES) cells our earlier data showed widespread changes in gene expression profiles, including decreased expression of the full length active isoform of Dnmt3b methyltransferase and concomitan...

TranscriptomicsSignaling Pathways Deferentially Affect RNA Polymerase II Initiation, Pausing, and Elongation in Human Cells: Estrogen dependent signaling in MCF-7 cells
We used Global Run-on and Sequencing (GRO-seq) to measure the rate of transcription elongation by RNA polymerase II (Pol II) following gene activation. We observed that Pol II elongation rates can vary as much as 4-fold at different genomic loci and in response to two distinct cellular signaling pa...
