TranscriptomicsGenome-wide localization of exosome components to active promoters and chromatin insulators in Drosophila
Chromatin insulators are functionally conserved DNA-protein complexes that are situated throughout the genome and organize independent transcriptional domains.  Previous work implicated RNA as an important cofactor in chromatin insulator activity, although the mechanisms by which RNA affects insulat...

TranscriptomicsExpression data from Drosophila S2 cells depleted of exosome subunits
The exosome complex and its' subunits are vital for proccessing and or degrading many cellular RNAs. We used microarrays to detail the global changes in mRNA levels in response to exosome subunit depletion. RNA was extracted from dsRNA treated S2 cells and hybridized using Affymetrix microarrays. We...

TranscriptomicsTranscriptome-wide Analysis of Exosome Targets in the Budding Yeast Saccharomyces cerevisiae
Purpose: The exosome plays major roles in RNA processing and surveillance but the in vivo target range and substrate acquisition mechanisms remain unclear. We applied an in vivo cross-linking technique coupled with deep sequencing (CRAC) that captures transcriptome-wide interactions between individu...

GenomicsThe RNA Exosome Promotes Transcription Termination of backtracked RNA Polymerase II
Large fractions of genomes are expressed in most eukaryotic cells, generating a diverse repertoire of protein-coding and non-coding transcripts. With such complexity, and as the number of mRNA molecules per cell are often low, it is clear that errors anywhere in the gene expression process could hav...

ProteomicsAn extended PAXT connection is required for turnover of nuclear polyadenylated RNA in human cells
Recruitment of the human ribonucleolytic RNA exosome to nuclear polyadenylated (pA+) RNA is facilitated by the Poly(A) Tail eXosome Targeting (PAXT) connection. Besides its core dimer, formed by the exosome co-factor MTR4 and the ZFC3H1 protein, the PAXT connection remains poorly defined. By charact...

TranscriptomicsThe roles of 3’-exoribonucleases and the exosome in trypanosome mRNA degradation
The roles of 3’-exoribonucleases and the exosome in trypanosome mRNA degradation; 30 min after actinomycin D +sinefungin, RNAi against CAf1, CNOT10, PAN2. These are really old data that hadn't been deposited.The datasets called RNA1, RNA2, RNA3 and RNA4 are almost certainly, from their location in t...

ProteomicsGlobal profiling and functional characterization of post-translational modifications of the fission yeast RNA exosome
The RNA exosome is a multi-subunit complex essential for processing and degradation of many classes of RNA. Although many of the functions of the RNA exosome are well established, how the activity of this complex is regulated remains poorly understood. Here we report a comprehensive proteomic analys...

Cut & Tag was used to localize the 3 mouse HP1 proteins (Cbx1,Cbx3,Cbx5) to the genome of BMEL (bipotential mouse embryonic liver) cells. Het BMEL cells are Cbx1+/+, Cbx3+/+, Cbx5+/- HP1-TKO (triple knock-out cells) are Cbx1-/-, Cbx3-/-, Cbx5-/-. The HP1_TKO cells were used to verify the specificity...
