Transcription Factor Binding to Replicated DNA
Cell Reports, 2020 Summary: Genome replication perturbs the DNA regulatory environment by displacing DNA-bound proteins, replacing nucleosomes, and introducing dosage imbalance between regions replicating at different S-phase stages.

Structure of the p53/RNA polymerase II assembly
Communications Biology, 2021 Liou et al. report a 4.6 Å resolution structure of the human p53/ RNA polymerase II assembly, using single particle cryoelectron microscopy. This study suggests that p53’s functional domains regulate the DNA binding activity of RNA polymerase II ...

Maintenance of long-range DNA interactions after inhibition of ongoing RNA polymerase II transcription. [PDF]
PLoS ONE, 2008 A relationship exists between nuclear architecture and gene activity and it has been proposed that the activity of ongoing RNA polymerase II transcription determines genome organization in the mammalian cell nucleus.

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

Human p53 interacts with the elongating RNAPII complex and is required for the release of actinomycin D induced transcription blockage [PDF]
, 2017 The p53 tumour suppressor regulates the transcription initiation of selected genes by binding to specific DNA sequences at their promoters. Here we report a novel role of p53 in transcription elongation in human cells.

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

Structural Transition of the Nucleosome during Transcription Elongation
Cells, 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 ...

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.

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.

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