H3K4me3 regulates RNA polymerase II promoter-proximal pause-release

open access: yesNature, 2023
Trimethylation of histone H3 lysine 4 (H3K4me3) is associated with transcriptional start sites and has been proposed to regulate transcription initiation^ 1 , 2 .

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.

A Movie of RNA Polymerase II Transcription [PDF]

open access: yesCell, 2012
We provide here a molecular movie that captures key aspects of RNA polymerase II initiation and elongation. To create the movie, we combined structural snapshots of the initiation-elongation transition and of elongation, including nucleotide addition, translocation, pausing, proofreading, backtracking, arrest, reactivation, and inhibition.

The Mediator complex as a master regulator of transcription by RNA polymerase II

open access: yesNature reviews. Molecular cell biology, 2022
The Mediator complex, which in humans is 1.4 MDa in size and includes 26 subunits, controls many aspects of RNA polymerase II (Pol II) function. Apart from its size, a defining feature of Mediator is its intrinsic disorder and conformational flexibility,

RNA Polymerase II: Just Stopping By [PDF]

open access: yesCell, 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 ...

Structure of an inactive RNA polymerase II dimer [PDF]

open access: yesNucleic Acids Research, 2021
Abstract Eukaryotic gene transcription is carried out by three RNA polymerases: Pol I, Pol II and Pol III. Although it has long been known that Pol I can form homodimers, it is unclear whether and how the two other RNA polymerases dimerize.

RNA polymerase II speed: a key player in controlling and adapting transcriptome composition

open access: yesEMBO Journal, 2021
RNA polymerase II (RNA Pol II) speed or elongation rate, i.e., the number of nucleotides synthesized per unit of time, is a major determinant of transcriptome composition.

RNA Polymerase II Elongation Control [PDF]

open access: yesAnnual 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

Mediator and RNA polymerase II clusters associate in transcription-dependent condensates

open access: yesScience, 2018
Phase separation and gene control Many components of eukaryotic transcription machinery—such as transcription factors and cofactors including BRD4, subunits of the Mediator complex, and RNA polymerase II—contain intrinsically disordered low-complexity ...

Different phosphorylated forms of RNA polymerase II and associated mRNA processing factors during transcription.

open access: yesGenes & Development, 2000
The activities of several mRNA processing factors are coupled to transcription through binding to RNA polymerase II (Pol II). The largest subunit of Pol II contains a repetitive carboxy-terminal domain (CTD) that becomes highly phosphorylated during ...
