Impact of template backbone heterogeneity on RNA polymerase II transcription. [PDF]

open access: yes, 2014
Variations in the sugar component (ribose or deoxyribose) and the nature of the phosphodiester linkage (3'-5' or 2'-5' orientation) have been a challenge for genetic information transfer from the very beginning of evolution.

The Block to Transcription Elongation at the Minute Virus of Mice Attenuator Is Regulated by Cellular Elongation Factors [PDF]

open access: yesMolecular and Cellular Biology, 1991
We have previously reported that both in vivo and in vitro, RNA polymerase II pauses or prematurely terminates transcription at a specific attenuation site located 142 to 147 nucleotides downstream from the P4 promoter of minute virus of mice (MVM). In this report, we show that an in vitro block to transcription elongation in HeLa whole-cell extract ...

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

open access: yesFEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Transcription as a Threat to Genome Integrity [PDF]

open access: yes, 2016
Genomes undergo different types of sporadic alterations, including DNA damage, point mutations, and genome rearrangements, that constitute the basis for evolution.

Transcription Elongation Factors in Health and Disease

open access: yes, 2022
Gene expression is a complex process that establishes and maintains a specific cell state. Transcription, an early event during the gene expression, is fine-tuned by a concerted action of a plethora of transcription factors temporally and spatially in response to various stimuli.

Maintenance of Transcription-Translation Coupling by Elongation Factor P

open access: yesmBio, 2016
ABSTRACT Under conditions of tight coupling between translation and transcription, the ribosome enables synthesis of full-length mRNAs by preventing both formation of intrinsic terminator hairpins and loading of the transcription termination factor Rho. While previous studies have focused on transcription factors, we investigated

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Knockdown of selenocysteine-specific elongation factor in Amblyomma maculatum alters the pathogen burden of Rickettsia parkeri with epigenetic control by the Sin3 histone deacetylase corepressor complex. [PDF]

open access: yesPLoS ONE, 2013
Selenocysteine is the 21st naturally-occurring amino acid. Selenoproteins have diverse functions and many remain uncharacterized, but they are typically associated with antioxidant activity.

Over-expression of a chimeric gene of the transcriptional co-activator MBF1 fused to the EAR repressor motif causes developmental alteration in Arabidopsis and tomato [PDF]

open access: yes, 2008
Transcriptional co-activators of the Multiprotein Bridging Factor1 (MBF1) type belong to a multigenic family that encode key components of the machinery controlling gene expression by communicating between transcription factors and the basal ...

Control of cotton fibre elongation by a homeodomain transcription factor GhHOX3 [PDF]

open access: yesNature Communications, 2014
AbstractCotton fibres are unusually long, single-celled epidermal seed trichomes and a model for plant cell growth, but little is known about the regulation of fibre cell elongation. Here we report that a homeodomain-leucine zipper (HD-ZIP) transcription factor, GhHOX3, controls cotton fibre elongation.GhHOX3genes are localized to the 12th homoeologous
