TranscriptomicsRate of elongation by RNA polymerase II is influenced by specific gene features and histone modifications
The rate of transcription elongation plays important roles in the timing of expression of full-length transcripts as well as for the regulation of alternative splicing. In this study we coupled Bru-Seq technology with 5,6-dichlorobenzimidazole 1-M-NM-2-D-ribofuranoside (DRB) to estimate the elongati...

GenomicsGlobal impact of RNA polymerase II elongation inhibition on alternative splicing regulation (ChIP-Seq)
The rate of RNA polymerase II (pol II) elongation can influence splice site selection in nascent transcripts, yet the extent and physiological relevance of this kinetic coupling between transcription and alternative splicing is not well understood. We performed experiments to perturb pol II elongati...

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...

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...

TranscriptomicsPostrecruitment Regulation of RNA Pol II Directs Rapid Signaling Responses at the Promoters of Estrogen Target Genes
Under current models for signal-dependent transcription in eukaryotes, DNA-binding activator proteins regulate the recruitment of RNA polymerase II (Pol II) to a set of target promoters. Yet, recent studies, as well as our results herein, show that Pol II is widely distributed (i.e., "preloaded") a...

GenomicsThreonine-4 of Mammalian RNA Polymerase II CTD is Targeted by Polo-like Kinase-3 and Required for Transcriptional Elongation
Eukaryotic RNA polymerase II (Pol II) has evolved an array of heptad repeats with the consensus sequence Tyr1-Ser2-Pro3-Thr4-Ser5-Pro6-Ser7 at the carboxy-terminal domain (CTD) of the large subunit (Rpb1). Differential phosphorylation of Ser2, Ser5, and Ser7 in the 5M-bM-^@M-^Y and 3M-bM-^@M-^Y regi...

TranscriptomicsHEK293T cells were transfected with the Rbp1-amr or slow (R729H-amr) α-amanitin resistant subunit of RNA Pol II and selected with α-amanitin 24 hours after transfection for additional 24 hours
HEK293T cells were transfected with the Rbp1-amr or slow (R729H-amr) α-amanitin resistant subunit of RNA Pol II and selected with α-amanitin 24 hours after transfection for additional 24 hours. Total RNA was extracted and global changes in gene expression were determined using microarray chips. Mi...

GenomicsBromodomain-Containing-Protein 4 (BRD4) Regulates RNA Polymerase II Serine 2 Phosphorylation in Human CD4+ T Cells
Transcriptional elongation by RNA polymerase II (Pol II) is regulated by positive transcription elongation factor b (P-TEFb) in association with Bromodomain-containing protein 4 (BRD4). We used genome-wide chromatin immunoprecipitation sequencing in primary human CD4+ T cells to reveal that BRD4 co-...
