CDK9-dependent RNA polymerase II pausing controls transcription initiation
eLife, 2017 Gene transcription can be activated by decreasing the duration of RNA polymerase II pausing in the promoter-proximal region, but how this is achieved remains unclear.

H3K4me3 regulates RNA polymerase II promoter-proximal pause-release
Nature, 2023 Trimethylation of histone H3 lysine 4 (H3K4me3) is associated with transcriptional start sites and has been proposed to regulate transcription initiation^ 1 , 2 .

The Mediator complex as a master regulator of transcription by RNA polymerase II
Nature reviews. Molecular cell biology, 2022 The Mediator complex, which in humans is 1.4 MDa in size and includes 26 subunits, controls many aspects of RNA polymerase II (Pol II) function. Apart from its size, a defining feature of Mediator is its intrinsic disorder and conformational flexibility,

RNA polymerase II speed: a key player in controlling and adapting transcriptome composition
EMBO Journal, 2021 RNA polymerase II (RNA Pol II) speed or elongation rate, i.e., the number of nucleotides synthesized per unit of time, is a major determinant of transcriptome composition.

Genetic dissection of the RNA polymerase II transcription cycle
eLife, 2022 How DNA sequence affects the dynamics and position of RNA Polymerase II (Pol II) during transcription remains poorly understood. Here, we used naturally occurring genetic variation in F1 hybrid mice to explore how DNA sequence differences affect the ...

Characterization of RNA polymerases from Rous sarcoma virus-induced mouse ascites sarcoma cells. [PDF]
, 1979 RNA polymerase was extracted from the Schmidt-Ruppin strain of Rous sarcoma virus (SR-RSV)-induced C3H/He mouse ascites sarcoma cells (SR-C3H). RNA polymerase was separated into RNA polymerases I and II by DEAE-Sephadex chromatography.

In vitro Assessment of RNA Polymerase I Activity
Bio-Protocol, 2017 In eukaryotic cells transcriptional processes are carried out by three different RNA polymerases: RNA polymerase I which specifically transcribes ribosomal RNA (rRNA), RNA polymerase II which transcribes protein-coding genes to yield messenger RNAs ...

A comparative study of DNA-dependent RNA polymerases from rat ascites hepatoma cell nuclei and from rat liver nuclei [PDF]
, 1975 DNA-dependent RNA polymerases (EC 2.7.7.6) were extracted and partially purified form the nuclei of rat ascites hepatoma cells (AH-130) induced by 4-dimethylaminoazobenzene.

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.

Genome-wide control of RNA polymerase II activity by cohesin. [PDF]
PLoS Genetics, 2013 Cohesin is a well-known mediator of sister chromatid cohesion, but it also influences gene expression and development. These non-canonical roles of cohesin are not well understood, but are vital: gene expression and development are altered by modest ...
