RNA Polymerase III, Ageing and Longevity
Frontiers in Genetics, 2021 Transcription in eukaryotic cells is performed by three RNA polymerases. RNA polymerase I synthesises most rRNAs, whilst RNA polymerase II transcribes all mRNAs and many non-coding RNAs. The largest of the three polymerases is RNA polymerase III (Pol III)

Nucleocapsid protein of SARS-CoV-2 phase separates into RNA-rich polymerase-containing condensates
Nature Communications, 2020 The etiologic agent of the Covid-19 pandemic is the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The viral membrane of SARS-CoV-2 surrounds a helical nucleocapsid in which the viral genome is encapsulated by the nucleocapsid protein. 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.

Mediator and RNA polymerase II clusters associate in transcription-dependent condensates
Science, 2018 Phase separation and gene control Many components of eukaryotic transcription machinery—such as transcription factors and cofactors including BRD4, subunits of the Mediator complex, and RNA polymerase II—contain intrinsically disordered low-complexity ...

A link between transcription fidelity and pausing in vivo [PDF]
, 2017 Pausing by RNA polymerase is a major mechanism that regulates transcription elongation but can cause conflicts with fellow RNA polymerases and other cellular machineries. Here, we summarize our recent finding that misincorporation could be a major source

An RNA polymerase ribozyme that synthesizes its own ancestor
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Life depends on the propagation of heritable information across successive generations. An RNA polymerase ribozyme was obtained by in vitro evolution that has an unprecedented level of activity in copying complex RNA templates.

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

alpha-helix E of Spo0A is required for sigma(A)- but not for sigma(H)-dependent promoter activation in Bacillus subtilis [PDF]
, 2004 At the onset of endospore formation in Bacillus subtilis, the DNA binding protein Spo0A activates transcription from two types of promoters. The first type includes the spoIIG and spoIIE promoters, which are used by sigma(A)-RNA polymerase, whereas the ...

Syn5 RNA polymerase synthesizes precise run-off RNA products [PDF]
, 2013 The enzyme predominantly used for in vitro run-off RNA synthesis is bacteriophage T7 RNA polymerase. T7 RNA polymerase synthesizes, in addition to run-off products of precise length, transcripts with an additional non-base-paired nucleotide at the 3 ...
