Role reversal of functional identity in host factors: Dissecting features affecting pro-viral versus antiviral functions of cellular DEAD-box helicases in tombusvirus replication.

open access: yesPLoS Pathogens, 2020
Positive-stranded (+)RNA viruses greatly exploit host cells to support viral replication. However, unlike many other pathogens, (+)RNA viruses code for only a limited number of genes, making them highly dependent on numerous co-opted host factors for ...

Caspase-Dependent Cleavage of DDX21 Suppresses Host Innate Immunity

open access: yesmBio, 2021
Innate immunity serves as the first barrier against virus infection. DEAD (Glu-Asp-Ala-Glu) box RNA helicases, originally considered to be involved in RNA processing and RNA unwinding, have been shown to play an important role in antiviral innate ...

p68 RNA helicase - identification of a nucleolar form and cloning of related genes containing a conserved intron in yeasts [PDF]

open access: yes, 2014
The human p68 protein is an RNA-dependent ATPase and RNA helicase which was first identified because of its immunological cross-reaction with a viral RNA helicase, simian virus 40 large T antigen.

Targeting transcription factors associated with hemoglobinopathies: Lessons from successful interventions and implications for cancer

open access: yesMolecular Oncology, EarlyView.
This review summarizes the transcription factors, repressive chromatin‐modifying complexes, and epigenetic mechanisms that control fetal hemoglobin repression. Notably, many regulators of γ‐globin silencing also function in transcriptional and epigenetic networks that drive cancer, highlighting opportunities to translate advances in hemoglobinopathy ...

SPHINX31 acts as a SRPK1 inhibitor targeting the ATR/DNA‐PKcs/CHK1 replicative checkpoint to inhibit cell growth in non‐small cell lung cancer

open access: yesMolecular Oncology, EarlyView.
The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.

RNA Helicases on the Move [PDF]

open access: yesBiophysical Journal, 2014
We have investigated the mechanical properties of the RNA-helicase-motor proteins in single-molecule assays using Magnetic Tweezers. RNA helicases are fundamental molecular motors that remodel RNA structures, DNA/RNA hybrids and RNA-protein complexes that are essential in gene regulation.

Closing in on ATPase Activity by an RNA Helicase [PDF]

open access: yesStructure, 2020
In this issue of Structure, Absmeier et al. (2020) describe the molecular mechanisms employed by an RNA helicase to prevent premature ATP hydrolysis upon nucleotide binding.

Selective pharmacological targeting of a DEAD box RNA helicase.

open access: yesPLoS ONE, 2008
RNA helicases represent a large family of proteins implicated in many biological processes including ribosome biogenesis, splicing, translation and mRNA degradation. However, these proteins have little substrate specificity, making inhibition of selected

RNA helicase domains of viral origin in proteins of insect retrotransposons: possible source for evolutionary advantages [PDF]

open access: yesPeerJ, 2017
Recently, a novel phenomenon of horizontal gene transfer of helicase-encoding sequence from positive-stranded RNA viruses to LINE transposons in insect genomes was described.

Small RNA pathways in mammalian oocytes

open access: yesFEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...
