(Submitter supplied) Promoter-proximal pausing of RNA polymerase II (Pol II) is a widespread in higher eukaryotes. Previous studies have shown that GAF is enriched at paused genes, but the role of GAF in pausing has not been well characterized on a genome-wide level. To investigate the role of GAF in pausing, we RNAi-depleted GAF from Drosophila S2 cells, and examined the effects on promoter-proximal polymerase. We confirmed the importance of GAF for pausing on the classic pause model gene Hsp70. more...

(Submitter supplied) GAGA associated transcription factor (GAF) is a highly abundant and essential protein in Drosophila. GAF recognizes and binds arrays of GA dinucleotides via a zinc finger DNA binding domain to regulate transcription by binding to general TF machinery or recruit nucleosome remodeling factors. We performed GAF ChIP-seq to quantify the intensity of GAF binding at high resolution in S2 cells. In addition, we performed GAF ChIP-seq in S2 cells that were depleted of GAF by RNAi. more...

(Submitter supplied) Transcription regulation occurs frequently through promoter-associated pausing of RNA polymerase II (Pol II). We developed a Precision nuclear Run-On and sequencing assay (PRO-seq) to map the genome-wide distribution of transcriptionally-engaged Pol II at base-pair resolution. Pol II accumulates immediately downstream of promoters, at intron-exon junctions that are efficiently used for splicing, and over 3' poly-adenylation sites. more...

(Submitter supplied) Transcription activation involves RNA polymerase II (Pol II) recruitment and release from the promoter into productive elongation, but how specific chromatin regulators control these steps is unclear. Here we identify a novel activity of the histone acetyltransferase p300/CBP in regulating promoter-proximal paused Pol II. We find that Drosophila CBP (nejire) inhibition impedes transcription through the +1 nucleosome leading to accumulation of Pol II at this position on all expressed genes. more...

(Submitter supplied) Transcription activation involves RNA polymerase II (Pol II) recruitment and release from the promoter into productive elongation, but how specific chromatin regulators control these steps is not fully understood. Here we identify a novel activity of the co-regulator and histone acetyltransferase p300/CBP in positioning promoter-proximal paused Pol II. We find that CBP inhibition impedes transcription through the +1 nucleosome, causing “dribbling” of Pol II from the canonical pause site genome-wide. more...

(Submitter supplied) RNA polymerase II (Pol II) is generally paused at promoter-proximal regions in most metazoans, and based on in vitro studies, this function has been attributed to the negative elongation factor (NELF). Here, we show that upon rapid depletion of NELF, Pol II fails to be released into gene bodies, stopping instead around the +1 nucleosomal dyad-associated region. The transition to the 2nd pause region is independent of positive transcription elongation factor P-TEFb. more...

(Submitter supplied) 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 promoters in metazoans implies that steps other than Pol II recruitment are rate-limiting and regulated 1-6. By integrating genome-wide Pol II chromatin immunoprecipition (ChIP) and Global Run-On (GRO) genomic data sets from Drosophila cells, we examined critical features of Pol II near promoters. more...

(Submitter supplied) Transcription initiation entails chromatin opening followed by pre-initiation complex formation and RNA Polymerase II recruitment. Subsequent polymerase elongation requires additional signals, resulting in increased residence time downstream of the start site, a phenomenon referred to as pausing. Here we harnessed single molecule footprinting to quantify distinct steps of initiation in vivo throughout the drosophila genome. more...
