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

A bumpy road for RNA polymerase II
Nature Structural & Molecular Biology, 2015 The identification of a second regulatory checkpoint controlling RNA polymerase II elongation near the poly(A) site of protein-coding genes reveals an additional level of complexity in the modulation of eukaryotic transcriptional elongation and termination.

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

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

Occupancy of chromatin organizers in the Epstein–Barr virus genome [PDF]
, 2011 The human CCCTC-binding factor, CTCF, regulates transcription of the double-stranded DNA genomes of herpesviruses. The architectural complex cohesin and RNA Polymerase II also contribute to this organization.

Dephosphorylating eukaryotic RNA polymerase II [PDF]
Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2016 The phosphorylation state of the C-terminal domain of RNA polymerase II is required for the temporal and spatial recruitment of various factors that mediate transcription and RNA processing throughout the transcriptional cycle. Therefore, changes in CTD phosphorylation by site-specific kinases/phosphatases are critical for the accurate transmission of ...

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.

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