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.

An RNA polymerase I enhancer in Saccharomyces cerevisiae. [PDF]
Molecular and Cellular Biology, 1986 By the use of an artificial gene coding for rRNA (rDNA gene), we found that transcription of the major precursor rRNA in Saccharomyces cerevisiae cells is stimulated 15-fold by a positive control element located 2 kilobases upstream of the transcription initiation site.

Molecular Structures of Transcribing RNA Polymerase I [PDF]
Molecular Cell, 2016 RNA polymerase I (Pol I) is a 14-subunit enzyme that solely synthesizes pre-ribosomal RNA. Recently, the crystal structure of apo Pol I gave unprecedented insight into its molecular architecture. Here, we present three cryo-EM structures of elongating Pol I, two at 4.0 Å and one at 4.6 Å resolution, and a Pol I open complex at 3.8 Å resolution.

Autophagy regulates rRNA synthesis
Nucleus, 2022 Autophagy has emerged as a key regulator of cell metabolism. Recently, we have demonstrated that autophagy is involved in RNA metabolism by regulating ribosomal RNA (rRNA) synthesis.

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.

eLife, 2015 Errors during transcription may play an important role in determining cellular phenotypes: the RNA polymerase error rate is >4 orders of magnitude higher than that of DNA polymerase and errors are amplified >1000-fold due to translation.

Partial Inhibition of RNA Polymerase I Promotes Animal Health and Longevity
Cell Reports, 2020 Summary: Health and survival in old age can be improved by changes in gene expression. RNA polymerase (Pol) I is the essential, conserved enzyme whose task is to generate the pre-ribosomal RNA (rRNA). We find that reducing the levels of Pol I activity is

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

RNA Biology, 2023 The main components of the essential cellular process of eukaryotic ribosome biogenesis are highly conserved from yeast to humans. Among these, the U3 Associated Proteins (UTPs) are a small subunit processome subcomplex that coordinate the first two ...

Identification of Five Putative Yeast RNA Helicase Genes [PDF]
, 1990 The RNA helicase gene family encodes a group of eight homologous proteins that share regions of sequence similarity. This group of evolutionarily conserved proteins presumably all utilize ATP (or some other nucleoside triphosphate) as an energy source ...
