Chromatin remodeling by Pol II primes efficient Pol III transcription
Nature Communications, 2023 The packaging of the genetic material into chromatin imposes the remodeling of this barrier to allow efficient transcription. RNA polymerase II activity is coupled with several histone modification complexes that enforce remodeling.

Nuclear Organization and Dynamics of 7SK RNA in Regulating Gene Expression [PDF]
, 2010 Noncoding RNAs play important roles in various aspects of gene regulation. We have identified 7SK RNA to be enriched in nuclear speckles or interchromatin granule clusters (IGCs), a subnuclear domain involved in pre-mRNA processing.

Structure of transcribing RNA polymerase II-nucleosome complex
Nature Communications, 2018 Eukaryotic transcription requires passage of RNA polymerase II (Pol II) through chromatin, which is impaired by nucleosomes. Here the authors report the cryo-EM structure of transcribing Pol II engaged with a downstream nucleosome core particle at an ...

SAF-A forms a complex with BRG1 and both components are required for RNA polymerase II mediated transcription. [PDF]
PLoS ONE, 2011 BACKGROUND: Scaffold attachment factor A (SAF-A) participates in the regulation of gene expression by organizing chromatin into transcriptionally active domains and by interacting directly with RNA polymerase II. METHODOLOGY: Here we use co-localization,

Attenuation of RNA polymerase II pausing mitigates BRCA1-associated R-loop accumulation and tumorigenesis. [PDF]
, 2017 Most BRCA1-associated breast tumours are basal-like yet originate from luminal progenitors. BRCA1 is best known for its functions in double-strand break repair and resolution of DNA replication stress.

Transcription start site scanning and the requirement for ATP during transcription initiation by RNA polymerase II [PDF]
, 2016 Saccharomyces cerevisiae RNA polymerase (Pol) II locates transcription start sites (TSS) at TATA-containing promoters by scanning sequences downstream from the site of preinitiation complex formation, a process that involves the translocation of ...

The RNA Polymerase II Factor RPAP1 Is Critical for Mediator-Driven Transcription and Cell Identity
Cell Reports, 2018 Summary: The RNA polymerase II-associated protein 1 (RPAP1) is conserved across metazoa and required for stem cell differentiation in plants; however, very little is known about its mechanism of action or its role in mammalian cells. Here, we report that

Bridge helix bending promotes RNA polymerase II backtracking through a critical and conserved threonine residue. [PDF]
, 2016 The dynamics of the RNA polymerase II (Pol II) backtracking process is poorly understood. We built a Markov State Model from extensive molecular dynamics simulations to identify metastable intermediate states and the dynamics of backtracking at atomistic
