Inhibition of post-transcriptional RNA processing by CDK inhibitors and its implication in anti-viral therapy.

open access: yesPLoS ONE, 2014
Cyclin-dependent kinases (CDKs) are key regulators of the cell cycle and RNA polymerase II mediated transcription. Several pharmacological CDK inhibitors are currently in clinical trials as potential cancer therapeutics and some of them also exhibit ...

Chromatin remodeling by Pol II primes efficient Pol III transcription

open access: yesNature 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.

Evolution and distribution of RNA polymerase II regulatory sites from RNA polymerase III dependant mobile Alu elements

open access: yesBMC Evolutionary Biology, 2004
Background The primate-specific Alu elements, which originated 65 million years ago, exist in over a million copies in the human genome. These elements have been involved in genome shuffling and various diseases not only through retrotransposition but ...

Structure of transcribing RNA polymerase II-nucleosome complex

open access: yesNature 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 ...

Effect of CFIm68 knockdown on RNA polymerase II transcription

open access: yesBMC Research Notes, 2019
Objectives Transcription of eukaryotic protein-coding genes by RNA polymerase II (pol II) is highly regulated at initiation, elongation and termination.

SAF-A forms a complex with BRG1 and both components are required for RNA polymerase II mediated transcription. [PDF]

open access: yesPLoS 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,

Genome-wide control of RNA polymerase II activity by cohesin.

open access: yesPLoS 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 ...

Modulation of RNA primer formation by Mn(II)-substituted T7 DNA primase

open access: yesScientific Reports, 2017
Lagging strand DNA synthesis by DNA polymerase requires RNA primers produced by DNA primase. The N-terminal primase domain of the gene 4 protein of phage T7 comprises a zinc-binding domain that recognizes a specific DNA sequence and an RNA polymerase ...

RNA Polymerase II CTD phosphatase Rtr1 fine-tunes transcription termination.

open access: yesPLoS Genetics, 2020
RNA Polymerase II (RNAPII) transcription termination is regulated by the phosphorylation status of the C-terminal domain (CTD). The phosphatase Rtr1 has been shown to regulate serine 5 phosphorylation on the CTD; however, its role in the regulation of ...
