Structure of cytoplasmic RNA polymerase II [PDF]

open access: yesNature Communications
RNA polymerase II (Pol II) must be assembled in the cytoplasm before it enters the nucleus, where it transcribes protein-coding genes. Although transcription by Pol II is intensively studied, how this central multi-subunit enzyme is made and the role of ...

DNA topological regulation in RNA polymerase II transcription [PDF]

open access: yesCellular & Molecular Biology Letters
RNA polymerase II (Pol II) is the main enzyme that synthesizes protein-coding messenger RNA and a subset of nonprotein coding RNA molecules based on the DNA sequences harboring genetic information in eukaryotes.

Sequential RNA polymerase II activation drives human hematopoiesis [PDF]

open access: yesCell Reports
Summary: Promoter-proximal pausing of RNA polymerase II (Pol II) primes genes for rapid activation, yet how Pol II dynamics are temporally organized in adult stem cells to enable fast and flexible responses to environmental cues remain unknown.

Single-molecule imaging reveals RNA polymerase II dynamics and TAF1-dependent promoter-proximal pause release [PDF]

open access: yesNature Communications
Early transcriptional regulation is a major kinetic bottleneck in gene expression, yet the dynamics of RNA polymerase II in living cells remain poorly understood.

RNA polymerase II pausing in development: orchestrating transcription

open access: yesOpen Biology, 2022
The coordinated regulation of transcriptional networks underpins cellular identity and developmental progression. RNA polymerase II promoter-proximal pausing (Pol II pausing) is a prevalent mechanism by which cells can control and synchronize ...

Extragenic accumulation of RNA polymerase II enhances transcription by RNA polymerase III. [PDF]

open access: yesPLoS Genetics, 2007
Recent genomic data indicate that RNA polymerase II (Pol II) function extends beyond conventional transcription of primarily protein-coding genes. Among the five snRNAs required for pre-mRNA splicing, only the U6 snRNA is synthesized by RNA polymerase ...

RNA polymerase II at initiation [PDF]

open access: yesProceedings of the National Academy of Sciences, 2003
RNA polymerase II (RNAPII) is the enzyme responsible for synthesis of all mRNA in higher cells. As the central component of the eukaryotic transcription machinery, RNAPII is the final target of regulatory pathways that are ultimately responsible for cellular development, differentiation, and metabolic control.

Genome-wide mapping of yeast RNA polymerase II termination. [PDF]

open access: yesPLoS Genetics, 2014
Yeast RNA polymerase II (Pol II) terminates transcription of coding transcripts through the polyadenylation (pA) pathway and non-coding transcripts through the non-polyadenylation (non-pA) pathway.

Regulation of Eukaryotic RNAPs Activities by Phosphorylation

open access: yesFrontiers in Molecular Biosciences, 2021
Evolutionarily conserved kinases and phosphatases regulate RNA polymerase II (RNAPII) transcript synthesis by modifying the phosphorylation status of the carboxyl-terminal domain (CTD) of Rpb1, the largest subunit of RNAPII.

RNA polymerase II: the elephant in the room. [PDF]

open access: yesTrends Genet
How genes respond to external signals is poorly understood, with transcription factors and histones proposed as mediators of signals to RNA polymerase II (Pol II). However, recent work shows that Pol II is the direct target of more than 100 protein kinases, a previously underappreciated mechanism for generating epigenetic complexity.
