A remodeled RNA polymerase II complex catalyzing viroid RNA-templated transcription.
PLoS Pathogens, 2022 Viroids, a fascinating group of plant pathogens, are subviral agents composed of single-stranded circular noncoding RNAs. It is well-known that nuclear-replicating viroids exploit host DNA-dependent RNA polymerase II (Pol II) activity for transcription ...

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 ...

Genetic dissection of the RNA polymerase II transcription cycle
eLife, 2022 How DNA sequence affects the dynamics and position of RNA Polymerase II (Pol II) during transcription remains poorly understood. Here, we used naturally occurring genetic variation in F1 hybrid mice to explore how DNA sequence differences affect the ...

In vitro Assessment of RNA Polymerase I Activity
Bio-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 ...

RNA Polymerase II Elongation Control [PDF]
Annual Review of Biochemistry, 2012 Regulation of the elongation phase of transcription by RNA polymerase II (Pol II) is utilized extensively to generate the pattern of mRNAs needed to specify cell types and to respond to environmental changes. After Pol II initiates, negative elongation factors cause it to pause in a promoter proximal position. These polymerases are poised to respond to

CDK9-dependent RNA polymerase II pausing controls transcription initiation
eLife, 2017 Gene transcription can be activated by decreasing the duration of RNA polymerase II pausing in the promoter-proximal region, but how this is achieved remains unclear.

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 ...

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 ...

RNA Polymerase II: Just Stopping By [PDF]
Cell, 2007 In this issue of Cell, Guenther et al. (2007) analyze the presence of chromatin marks and RNA polymerase at transcription start sites in the human genome. Their results reveal that many "inactive" genes harbor histone marks associated with active transcription at their 5' ends and that although these genes initiate transcription, they do not generate ...
