GenomicsGenomic Study of RNA Polymerase II and III SNAPc-Bound Promoters Reveals a Gene Transcribed by both Enzymes and a Broad Use of Common Activators
SNAPc-dependent promoters are unique among cellular promoters in being very similar to each other, even though some of them recruit RNA polymerase II and other RNA polymerase III. We have examined all SNAPc-bound promoters present in the human genome. We find that there is a surprisingly small numbe...

GenomicsHuman RNA polymerase III transcriptomes and relationships to Pol II promoter chromatin and enhancer-binding factors.
RNA polymerase (Pol) III transcribes many noncoding RNAs (for example, transfer RNAs) important for translational capacity and other functions. We localized Pol III, alternative TFIIIB complexes (BRF1 or BRF2) and TFIIIC in HeLa cells to determine the Pol III transcriptome, define gene classes and r...

GenomicsGenome-wide mapping of RNA Pol III binding site (GM12878)
We report the results of chromatin immunoprecipitation following by high-thoughput sequencing (ChIP-Seq) using the GA II platform from Illumina for the human RNA Polymerase III in GM12878 cells. We have also generated a sequenced input DNA datasets for GM12878 cells. For data usage terms and condi...

GenomicsGenome-wide mapping of RNA Pol III binding site (K562)
We report the results of chromatin immunoprecipitation following by high-thoughput tag sequencing (ChIP-Seq) using the GA II platform from Illumina for the human RNA Polymerase III in K562 cells. We have also generated a sequenced input DNA datasets for K562 cells. For data usage terms and conditi...

ProteomicsRNA polymerase III interactome
Many regulatory proteins and complexes have been identified which influence transcription by RNA polymerase (pol) II with a fine precision. In comparison, only a few regulatory proteins are known for pol III, which transcribes mostly house-keeping and non-coding RNAs. Yet, pol III transcription is p...

GenomicsGenome-wide localization of the RNA polymerase III transcription machinery in human cells
To characterize the pol III transcriptome in actively growing human cells, we used MR90hTeIrt lung fibroblasts, which are immortal but not transformed, with an intact Rb pathway. After formaldehyde cross-linking, chromatin was extracted and submitted to immunoprecipitation. To identify actively tr...

TranscriptomicsRNA Pol III transcriptomes and relationships to Pol II promoters, enhancer-binding factors and chromatin domains
RNA polymerase III transcribes many noncoding RNAs (e.g. tRNAs) important for translational capacity and other functions. Here, we localized RNA polymerase III, alternative TFIIIB complexes (BRF1/2) and TFIIIC in HeLa cells, determining the Pol III transcriptome, defining gene classes, and reveali...

ProteomicsRiluzole partially restores RNA polymerase III complex assembly in cells expressing the leukodystrophy-causative variant POLR3B R103H
The mechanism of assembly of RNA polymerase III (Pol III), the 17-subunit enzyme that synthesizes tRNAs, 5S rRNA, and other small-nuclear (sn) RNAs in eukaryotes, is not clearly understood. The recent discovery of the HSP90 co-chaperone PAQosome (Particle for Arrangement of Quaternary structure) rev...

ProteomicsRNA polymerase III (Pol III) CoIP ms/ms
RNA polymerase III (Pol III) synthesizes noncoding RNAs essential for translation, RNA processing, transcription regulation, and other core cellular processes. Pol III transcription levels are coordinated with nutrient availability for cellular growth, and its dysregulation is linked to disease, suc...

ProteomicsSubcellular Localization Shapes the Fate of RNA Polymerase III-2
RNA Pol III plays a vital role in transcription and as a viral-DNA sensor, but how it is assembled and distributed within cells remain poorly understood. Here, we show that Pol III is assembled with chaperones in the cytoplasm and forms transcription-dependent protein clusters upon transport into th...
