A direct role of RNA polymerase III and RNA in DNA homologous recombination

open access: yesMolecular & Cellular Oncology, 2021
End resection excises several thousand bases from the 5ʹ-ended strand during DNA double-strand break repair, creating 3ʹ-end single-stranded DNA overhangs. This overhang requires strict protection from DNA2 or other nucleases digestion.

Transcriptional response to VZV infection is modulated by RNA polymerase III in lung epithelial cell lines

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
Ancestral RNA polymerase III (Pol III) is a multi-subunit polymerase responsible for transcription of short non-coding RNA, such as double-stranded short interspersed nuclear elements (SINEs).

In vitro Assessment of RNA Polymerase I Activity

open access: yesBio-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 ...

Specific Features of RNA Polymerases I and III: Structure and Assembly

open access: yesFrontiers in Molecular Biosciences, 2021
RNA polymerase I (RNAPI) and RNAPIII are multi-heterogenic protein complexes that specialize in the transcription of highly abundant non-coding RNAs, such as ribosomal RNA (rRNA) and transfer RNA (tRNA).

Truncated PARP1 mediates ADP-ribosylation of RNA polymerase III for apoptosis

open access: yesCell Discovery, 2022
Caspase-mediated cleavage of PARP1 is a surrogate marker for apoptosis. However, the biological significance of PARP1 cleavage during apoptosis is still unclear.

Retrotransposon targeting to RNA polymerase III-transcribed genes

open access: yesMobile DNA, 2018
Retrotransposons are genetic elements that are similar in structure and life cycle to retroviruses by replicating via an RNA intermediate and inserting into a host genome. The Saccharomyces cerevisiae (S.

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 ...

Novel layers of RNA polymerase III control affecting tRNA gene transcription in eukaryotes [PDF]

open access: yesOpen Biology, 2017
RNA polymerase III (Pol III) transcribes a limited set of short genes in eukaryotes producing abundant small RNAs, mostly tRNA. The originally defined yeast Pol III transcriptome appears to be expanding owing to the application of new methods.

RNA polymerase III transcription in cancer: the BRF2 connection

open access: yesMolecular Cancer, 2011
RNA polymerase (pol) III transcription is responsible for the transcription of small, untranslated RNAs involved in fundamental metabolic processes such mRNA processing (U6 snRNA) and translation (tRNAs).

Maf1 and Repression of RNA Polymerase III-Mediated Transcription Drive Adipocyte Differentiation

open access: yesCell Reports, 2018
Summary: RNA polymerase (pol) III transcribes a variety of small untranslated RNAs involved in transcription, RNA processing, and translation. RNA pol III and its components are altered in various human developmental disorders, yet their roles in cell ...
