Mechanism of RNA polymerase II stalling by DNA alkylation [PDF]

open access: yesProceedings of the National Academy of Sciences, 2017
Significance RNA polymerase II (Pol II) catalyzes the transcription of DNA to RNA in the nucleus. DNA alkylating cancer drugs can stall transcription; however, the basis for Pol II stalling when encountering a DNA template with minor-groove alkylation adducts has remained elusive due to its inherent chemical instability.

Mechanism of Rad26-assisted rescue of stalled RNA polymerase II in transcription-coupled repair

open access: yesNature Communications, 2021
Here the authors provide models of RNA polymerase II bound to the yeast CSB ortholog Rad26 in different nucleotide states; explain how Rad26 domain motions help the polymerase progress past DNA lesions; and interpret the effects of CSB-associated disease

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 ...

The menin tumor suppressor protein is phosphorylated in response to DNA damage. [PDF]

open access: yesPLoS ONE, 2011
Multiple endocrine neoplasia type 1 (MEN1) is a heritable cancer syndrome characterized by tumors of the pituitary, pancreas and parathyroid. Menin, the product of the MEN1 gene, is a tumor suppressor protein that functions in part through the regulation

Autophagy receptor NDP52 alters DNA conformation to modulate RNA polymerase II transcription

open access: yesNature Communications, 2023
NDP52 is an autophagy receptor involved in the recognition and degradation of invading pathogens and damaged organelles. Although NDP52 was first identified in the nucleus and is expressed throughout the cell, to date, there is no clear nuclear functions

Dpb11, which interacts with DNA polymerase II(epsilon) in Saccharomyces cerevisiae, has a dual role in S-phase progression and at a cell cycle checkpoint.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1995
DPB11, a gene that suppresses mutations in two essential subunits of Saccharomyces cerevisiae DNA polymerase II(epsilon) encoded by POL2 and DPB2, was isolated on a multicopy plasmid.

SnapShot: DNA Polymerases II Mammals

open access: yesCell, 2010
DNA polymerases ensure the faithful duplication of genetic information inside the nuclease and mitochondria of eukaryotic cells and the nucleoid of prokaryotic cells. These remarkable enzymes synthesize polynucleotide chains based on the complementarity of an incoming nucleotide to an existing DNA template. DNA polymerases are grouped into six families

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 ...
