Evidence for DNA-mediated nuclear compartmentalization distinct from phase separation [PDF]

open access: yeseLife, 2019
RNA Polymerase II (Pol II) and transcription factors form concentrated hubs in cells via multivalent protein-protein interactions, often mediated by proteins with intrinsically disordered regions.

HIF-1 Interacts with TRIM28 and DNA-PK to release paused RNA polymerase II and activate target gene transcription in response to hypoxia

open access: yesNature Communications, 2022
Hypoxia-inducible factor-1 (HIF-1) is a transcription factor that modulates target gene expression in response to changes in oxygen availability. Here the authors show that HIF-1 forms a complex with TRIM28 and DNA-dependent protein kinase (DNA-PK) that ...

Mechanism of Translesion DNA Synthesis by DNA Polymerase II [PDF]

open access: yesJournal of Biological Chemistry, 1996
Bypass synthesis by DNA polymerase II was studied using a synthetic 40-nucleotide-long gapped duplex DNA containing a site-specific abasic site analog, as a model system for mutagenesis associated with DNA lesions.

Somatic mutations in angiogenesis-related pathways and RNA polymerase II activity in sporadic brain arteriovenous malformations [PDF]

open access: yesFrontiers in Neurology
BackgroundSporadic brain arteriovenous malformations (bAVMs) are rare vascular anomalies characterized by abnormal angiogenesis and direct arteriovenous shunting.

RNA polymerase II is a polar roadblock to a progressing DNA fork [PDF]

open access: yesNature Communications
Transcription–replication conflicts threaten genome stability. Although head-on conflicts are more detrimental and prone to R-loop formation than co-directional conflicts, the cause of this RNA polymerase roadblock polarity remains unclear, and proposed ...

The cooperative action of CSB, CSA, and UVSSA target TFIIH to DNA damage-stalled RNA polymerase II

open access: yesNature Communications, 2020
The response to DNA damage-stalled RNA polymerase II leads to the assembly of the transcription-coupled repair (TCR) complex on actively transcribed strands. Here, the authors reveal the complex assembly mechanism of the TCR complex in human cells.

Alternative DNA secondary structure formation affects RNA polymerase II promoter-proximal pausing in human

open access: yesGenome Biology, 2018
Background Alternative DNA secondary structures can arise from single-stranded DNA when duplex DNA is unwound during DNA processes such as transcription, resulting in the regulation or perturbation of these processes. We identify sites of high propensity

Molecular mechanism of co-transcriptional H3K36 methylation by SETD2 [PDF]

open access: yesNature Communications
H3K36me3 is a hallmark of actively and recently transcribed genes and contributes to cellular memory and identity. The deposition of H3K36me3 occurs co-transcriptionally when the methyltransferase SETD2 associates with RNA polymerase II.

Mechanism of RNA polymerase II stalling by DNA alkylation

open access: yesProceedings of the National Academy of Sciences, 2017
Significance RNA polymerase II (Pol II) catalyzes the transcription of DNA to RNA in the nucleus. DNA alkylating cancer drugs can stall transcription; however, the basis for Pol II stalling when encountering a DNA template with minor-groove alkylation ...

Processive DNA synthesis by DNA polymerase II mediated by DNA polymerase III accessory proteins.

open access: yesJournal of Biological Chemistry, 1992
An interesting property of the Escherichia coli DNA polymerase II is the stimulation in DNA synthesis mediated by the DNA polymerase III accessory proteins beta,gamma complex. In this paper we have studied the basis for the stimulation in pol II activity and have concluded that these accessory proteins stimulate pol II activity by increasing the ...
