Transcription-associated breaks in Xeroderma Pigmentosum group D cells from patients with combined features of Xeroderma Pigmentosum and Cockayne Syndrome [PDF]

open access: yes, 2005
Defects in the XPD gene can result in several clinical phenotypes, including xeroderma pigmentosum (XP), trichothiodystrophy, and, less frequently, the combined phenotype of XP and Cockayne syndrome (XP-D/CS).

RNA polymerase II stalling promotes nucleosome occlusion and pTEFb recruitment to drive immortalization by Epstein-Barr virus [PDF]

open access: yes, 2011
Epstein-Barr virus (EBV) immortalizes resting B-cells and is a key etiologic agent in the development of numerous cancers. The essential EBV-encoded protein EBNA 2 activates the viral C promoter (Cp) producing a message of ~120 kb that is differentially ...

Escherichia coli DNA polymerase II is stimulated by DNA polymerase III holoenzyme auxiliary subunits

open access: yesJournal of Biological Chemistry, 1991
DNA polymerase III of Escherichia coli requires multiple auxiliary factors to enable it to serve as a replicative complex. We demonstrate that auxiliary components of the DNA polymerase III holoenzyme, the gamma delta complex and beta subunit, markedly stimulate DNA polymerase II on long single-stranded templates. DNA polymerase II activity is enhanced

RNA Pol II promotes transcription of centromeric satellite DNA in beetles. [PDF]

open access: yesPLoS ONE, 2008
Transcripts of centromeric satellite DNAs are known to play a role in heterochromatin formation as well as in establishment of the kinetochore.

Identification of functional cis-regulatory elements by sequential enrichment from a randomized synthetic DNA library [PDF]

open access: yes, 2013
BACKGROUND: The identification of endogenous cis-regulatory DNA elements (CREs) responsive to endogenous and environmental cues is important for studying gene regulation and for biotechnological applications but is labor and time intensive. Alternatively,

Aphidicolin inhibits DNA polymerase II ofEscherichia coli, an alpha-like DNA polymerase

open access: yesNucleic Acids Research, 1990
The polB gene of E. coli encodes DNA polymerase II. We have reported the cloning (1,2) and sequencing of the polB gene (3) (GenBank Accession number M35371). DNA polymerase II appears to be a non-essential function since the polB gene is missing from some widely used strains (3). Several sub-families of DNA polymerases have been identified (4). In this

Genetic dissection of the RNA polymerase II transcription cycle

open access: yeseLife, 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 ...

The Escherichia coli polB Locus Is Identical to dinA, the Structural Gene for DNA Polymerase II

open access: yesJournal of Biological Chemistry, 1997
Escherichia coli DNA polymerase II (Pol II) is a member of the group B, “α-like” family of DNA polymerases. Pol II is encoded by the damage-inducible dinA gene and exhibits SOS induction under the control of Lex A repressor.

Defective DNA repair mechanisms in prostate cancer: impact of olaparib [PDF]

open access: yes, 2017
The field of prostate oncology has continued to change dramatically. It has truly become a field that is intensely linked to molecular genetic alterations, especially DNA-repair defects.
