TranscriptomicsTranscription Initiation Activity Sets Replication Origin Efficiency in Mammalian Cells
Genomic mapping of DNA replication origins (ORIs) in mammals provides a powerful means for understanding the regulatory complexity of our genome. Here we combine a genome-wide approach to identify preferential sites of DNA replication initiation at 0.4% of the mouse genome with detailed molecular an...

ProteomicsBRD2 interconnects with BRD3 to facilitate Pol II transcription initiation and elongation to prime promoters for cell differentiation
Understanding the precise functions and relationship of BRD2 with other bromodomain and extraterminal motif (BET) proteins is central for the application of BET-specific and pan inhibitors. Here, we used acute protein degradation and quantitative genomic and proteomic approaches to investigate the p...

TranscriptomicsTranscription Initiation Platforms and GTF recruitment at tissue-specific enhancers and promoters
Recent works have shown that RNA Polymerase (Pol) II can be recruited to, and transcribe, distal regulatory regions. Here, we analyzed transcription initiation and elongation through genome-wide localization of Pol II, General Transcription Factors (GTFs) and active chromatin in developing T-cells. ...

TranscriptomicsStably-paused genes revealed through inhibition of transcription initiation by the TFIIH inhibitor Triptolide
Transcription by RNA Polymerase II (Pol II) in metazoan is regulated in several steps, including preinitiation complex (PIC) formation, initiation, Pol II escape, productive elongation, cotranscriptional RNA-processing and termination. Genome-wide studies have demonstrated that the phenomenon of ...

TranscriptomicsNuclear-localized tiny RNAs are associated with transcription initiation and splice sites in metazoans
We have recently shown that transcription initiation RNAs (tiRNAs) are derived from sequences downstream of transcription start sites. Here we report the identification of a second class of nuclear-specific ~17-18 nucleotide small RNA whose 3M-bM-^@M-^Y ends map precisely to the splice donor site of...

TranscriptomicsGlucose depletion inhibits translation initiation in yeast - transcription profiling
This is a transcription profiling study on yeast undergoing glucose depletion. It reveals that glucose depletion inhibits translation initiation in a mechanism involving eIF4A loss and 48S pre-initiation complex accumulation, while the pentose phosphate pathway is co-ordinately up-regulated

GenomicsIdentification of the primary target of the chemotherapeutic agent CX-5461 as a late step in transcription initiation by RNA Polymerase I
In recent years, several small molecule cytotoxic drugs have been identified as potential inhibitors of ribosome biogenesis (Drygin et al., 2011; Peltonen et al., 2014a; Peltonen et al., 2014b). CX-5461 is one such drug that has also demonstrated anticancer potential for a wide range of malignancies...

TranscriptomicsMultiple roles for LEC in initiation and elongation phases of snRNA gene transcription
The small nuclear RNA (snRNA) genes have been widely used as a model system for understanding transcriptional regulation due to unique aspects of their promoter structure, selectivity for either RNA Polymerase (Pol) II or III and a unique mechanism of termination that is tightly linked with the prom...
