The RNA Polymerase II Factor RPAP1 Is Critical for Mediator-Driven Transcription and Cell Identity

open access: yesCell Reports, 2018
Summary: The RNA polymerase II-associated protein 1 (RPAP1) is conserved across metazoa and required for stem cell differentiation in plants; however, very little is known about its mechanism of action or its role in mammalian cells. Here, we report that

THOC5 complexes with DDX5, DDX17, and CDK12 to regulate R loop structures and transcription elongation rate

open access: yesiScience, 2023
Summary: THOC5, a member of the THO complex, is essential for the 3′processing of some inducible genes, the export of a subset of mRNAs and stem cell survival.

Impact of template backbone heterogeneity on RNA polymerase II transcription. [PDF]

open access: yes, 2014
Variations in the sugar component (ribose or deoxyribose) and the nature of the phosphodiester linkage (3'-5' or 2'-5' orientation) have been a challenge for genetic information transfer from the very beginning of evolution.

Nucleolar RNA polymerase II drives ribosome biogenesis

open access: yesNature, 2020
Proteins are manufactured by ribosomes—macromolecular complexes of protein and RNA molecules that are assembled within major nuclear compartments called nucleoli 1 , 2 .

Cap-specific terminal N6-methylation of RNA by an RNA polymerase II–associated methyltransferase

open access: yesScience, 2019
A cap-specific m6A writer N6,2′-O-dimethyladenosine (m6Am) is present at the transcription start nucleotide of capped mRNAs in vertebrates. Akichika et al.

Modulation of RNA primer formation by Mn(II)-substituted T7 DNA primase

open access: yesScientific Reports, 2017
Lagging strand DNA synthesis by DNA polymerase requires RNA primers produced by DNA primase. The N-terminal primase domain of the gene 4 protein of phage T7 comprises a zinc-binding domain that recognizes a specific DNA sequence and an RNA polymerase ...

SAF-A forms a complex with BRG1 and both components are required for RNA polymerase II mediated transcription. [PDF]

open access: yesPLoS ONE, 2011
BACKGROUND: Scaffold attachment factor A (SAF-A) participates in the regulation of gene expression by organizing chromatin into transcriptionally active domains and by interacting directly with RNA polymerase II. METHODOLOGY: Here we use co-localization,

Writing a wrong: Coupled RNA polymerase II transcription and RNA quality control [PDF]

open access: yes, 2019
Processing and maturation of precursor RNA species is coupled to RNA polymerase II transcription. Co-transcriptional RNA processing helps to ensure efficient and proper capping, splicing, and 3' end processing of different RNA species to help ensure ...

Actively transcribing RNA polymerase II concentrates on spliced leader genes in the nucleus of Trypanosoma cruzi [PDF]

open access: yes, 2005
RNA polymerase II of trypanosomes, early diverging eukaryotes, transcribes long polycistronic messages, which are not capped but are processed by trans-splicing and polyadenylation to form mature mRNAs.

Structure of transcribing RNA polymerase II-nucleosome complex

open access: yesNature Communications, 2018
Eukaryotic transcription requires passage of RNA polymerase II (Pol II) through chromatin, which is impaired by nucleosomes. Here the authors report the cryo-EM structure of transcribing Pol II engaged with a downstream nucleosome core particle at an ...
