The largest subunit of human RNA polymerase III is closely related to the largest subunit of yeast and trypanosome RNA polymerase III [PDF]

open access: yes, 1997
In both yeast and mammalian systems, considerable progress has been made toward the characterization of the transcription factors required for transcription by RNA polymerase III. However, whereas in yeast all of the RNA polymerase III subunits have been

Dephosphorylating eukaryotic RNA polymerase II [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2016
The phosphorylation state of the C-terminal domain of RNA polymerase II is required for the temporal and spatial recruitment of various factors that mediate transcription and RNA processing throughout the transcriptional cycle. Therefore, changes in CTD phosphorylation by site-specific kinases/phosphatases are critical for the accurate transmission of ...

Characterization of human RNA polymerase III identifies orthologues for Saccharomyces cerevisiae RNA polymerase III subunits [PDF]

open access: yes, 2002
Unlike Saccharomyces cerevisiae RNA polymerase III, human RNA polymerase III has not been entirely characterized. Orthologues of the yeast RNA polymerase III subunits C128 and C37 remain unidentified, and for many of the other subunits, the available ...

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 ...

Impact of template backbone heterogeneity on RNA polymerase II transcription. [PDF]

open access: yes, 2014
Variations in the sugar component (ribose or deoxyribose) and the nature of the phosphodiester linkage (3'-5' or 2'-5' orientation) have been a challenge for genetic information transfer from the very beginning of evolution.

RNA elements directing in vivo assembly of the 7SK/MePCE/Larp7 transcriptional regulatory snRNP [PDF]

open access: yes, 2013
Through controlling the nuclear level of active positive transcription elongation factor b (P-TEFb), the 7SK small nuclear RNA (snRNA) functions as a key regulator of RNA polymerase II transcription.

A global function for transcription factors in assisting RNA polymerase II termination. [PDF]

open access: yes, 2017
The role of transcription factors (TFs) on nucleosome positioning, RNA polymerase recruitment, and transcription initiation has been extensively characterized.

RNA Polymerase II: Just Stopping By [PDF]

open access: yesCell, 2007
In this issue of Cell, Guenther et al. (2007) analyze the presence of chromatin marks and RNA polymerase at transcription start sites in the human genome. Their results reveal that many "inactive" genes harbor histone marks associated with active transcription at their 5' ends and that although these genes initiate transcription, they do not generate ...

Structural Transition of the Nucleosome during Transcription Elongation

open access: yesCells, 2023
In eukaryotes, genomic DNA is tightly wrapped in chromatin. The nucleosome is a basic unit of chromatin, but acts as a barrier to transcription. To overcome this impediment, the RNA polymerase II elongation complex disassembles the nucleosome during ...

Rrd1 isomerizes RNA polymerase II in response to rapamycin [PDF]

open access: yes, 2010
International audienceBACKGROUND: In Saccharomyces cerevisiae, the immunosuppressant rapamycin engenders a profound modification in the transcriptional profile leading to growth arrest.
