Coilin and Pol II ChIP-seq in HeLa cells after RPL14 and RPL24 depletion

Project description:To investigate location of Cajal bodies (CB) inside the cell nucleus after RPL depletion, we performed ChIP-seq with an anti-Coilin antibody after siRNA knockdown of RPL14 and RPL24. ChIP-seq revealed a loss of association of CBs wih snRNA genes and histone genes in histone cluster 1 and 2 upon RPL KD. We also performed Pol 2 ChIP-seq to look at transcription of these gene loci upon RPL knockdown and found decreased Pol II binding along genes.

Project description:We generated genome-wide maps of Pol II and Flag-LARP7 in human HeLa cells. We find that Flag-LARP7 and Pol II co-locolize on Pol II-specific sn/snoRNA genes.

Genome-wide analysis of distribution of RNA Pol II ChIP-seq in NKAP depletion cells

Project description:We performed ChIP-Seq analysis with an antibody against RNA polymerase II (Pol II). We found that the distribution of Pol II signals was decreased at the transcription start sites (TSSs) and transcription end sites (TESs) upon depletion of NKAP.

Targeted protein degradation reveals Pol II heterogeneity and functional diversity

Project description:RNA polymerase II (Pol II) subunits are thought to be involved in various transcription-associated processes, but it is unclear whether they play different regulatory roles in modulating gene expression. Here, we performed nascent and mature transcript sequencing after the acute degradation of 12 mammalian Pol II subunits and profiled their genomic binding sites and protein interactomes to dissect their molecular functions. We found that Pol II subunits contribute differently to Pol II cellular localization and transcription process and preferentially regulate RNA processing (such as RNA splicing and 3’ end maturation). Genes sensitive to the depletion of different Pol II subunits tend to be involved in diverse biological functions and show different RNA half-lives. Sequences, associated protein factors, and RNA structures are correlated with Pol II subunit-mediated differential gene expression. These findings collectively suggest that the heterogeneity of Pol II and different genes appear to depend on some of the subunits.

Pol II Ser7phospho ChIP-seq in mES cells

Project description:RNA Polymerase II transcribes protein-coding and many non-coding RNA genes in eukaryotes. The largest subunit of RNA Polymerase II, Rpb1, contains a hepta-peptide repeat on its C-terminal tail with three potential phosphorylation sites (Serine 2, Serine 5 and Serine 7). Mammalian Rpb1 contains 52 repeats. The phosphorylation events are catalyzed by specific protein kinases where the phosphorylation of specific residues is coupled to the transcription cycle. For example, the Cdk7 subunit of TFIIH phosphorylates both Serine 5 and Serine 7 during intiation and the Cdk9 subunit of P-TEFb phosphorylates Serine 2 during the transition into productive elongation. The dataset presented here is the genome-wide distribution of RNA Pol II with Serine 7 of the CTD phosphorylated in murine embryonic stem cells. This data, in addition to phospho-specific datasets generated in the same cell type in Rahl et al. Cell 2010 and Seila et al. Science 2008, represents the genome-wide distribution of multiple RNA Pol II isoforms in murine embryonic stem cells: total Pol II, hypophosphorylated CTD Pol II, Serine 2 phosphorylated CTD Pol II, Serine 5 phosphorylated CTD Pol II and Serine 7 phosphorylated CTD Pol II. An antibody specific to RNA Pol II Serine 7 phosphorylated CTD (gift of Dirk Eick; Chapman et al. Science 2008) was used to enrich for DNA fragments associated with this Pol II isoform in murine embryonic stem cells. DNA was purified and prepared for Illumina/Solexa sequencing following their standard protocol. This is a single dataset but together with datasets from Rahl et al. Cell 2010 and Seila et al. Science 2008, these datasets represent the genome-wide distribution of multiple RNA Pol II isoforms in murine embryonic stem cells: total Pol II, hypophosphorylated CTD Pol II, Serine 2 phosphorylated CTD Pol II, Serine 5 phosphorylated CTD Pol II and Serine 7 phosphorylated CTD Pol II.

Genome-wide map of RNA polymerase II, NELF, and DSIF in HeLa cells

Project description:Most metazoan promoters have RNA polymerase II (Pol II) paused slightly downstream of the transcription start site by NELF and DSIF. This pausing keeps these promoters available for rapid induction by P-TEFb, whose activity causes NELF to dissociate and Pol II and DSIF to elongate on the gene. ChIP-Seq data was generated for Pol II, NELF, and DSIF in HeLa cells and used to look at pausing downstream of unannotated promoters. 3x ChIP-Seq (Pol II, NELF, DSIF) in HeLa cells

Chromatin remodeling by antisense Pol II primes efficient Pol III transcription

Project description:The packaging of the genetic material into chromatin imposes the remodeling of this barrier to allow efficient transcription. RNA polymerase II activity is associated with several histone modification complexes that enforce remodeling. How RNA polymerase III (Pol III) counteracts the inhibitory effect of chromatin is unknown. We report here that antisense RNA Polymerase II (Pol II) transcription is critical to prime and maintain nucleosome depletion at Pol III loci and allow efficient Pol III recruitment upon re-initiation of growth from stationary phase. Antisense Pol II is recruited by the Pcr1 transcription factor, which affects local histone occupancy through the associated SAGA complex and a Pol II phospho-S2 CTD / Mst2 pathway. These data expand the central role of Pol II in gene expression beyond mRNA synthesis.

Pol II and its associated epigenetic marks are present at pol III-transcribed non-coding RNA genes (I)

Project description: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 genome. This reveals that the chromatin landscape of pol III-transcribed genes resembles that of pol II templates in many ways, although there are also clear differences. Our analysis also discovered an entirely unexpected phenomenon, namely that pol II co-localizes with the majority of genomic loci that are bound by pol III. Chip-Seq experiments for six samples: Pol III, TFIIIB, TFIIIC, H3K4me3 in HeLa cells and Pol III, S2 phos Pol II in CD4+ cells.
