DEAD-Box RNA Helicases in Gram-Positive RNA Decay

open access: yes, 2012
DEAD-box RNA helicases are important players in eukaryotic and bacterial RNA metabolism. A helicase from Staphylococcus aureus was recently shown to affect RNA decay, most likely via its interaction with the proposed Gram-positive degradosome. Some, but not all, RNAs are stabilized when the helicase CshA is mutated, and among the affected RNAs is the ...

Structural basis for RNA-duplex unwinding by the DEAD-box helicase DbpA [PDF]

open access: yesRNA, 2022
Abstract DEAD-box RNA helicases are implicated in most aspects of RNA biology, where these enzymes unwind short RNA duplexes in an ATP-dependent manner. During the central step of the unwinding cycle, the two domains of the helicase core form a distinct closed conformation that destabilizes the RNA duplex, which ultimately leads to ...

Role of DEAD/DEAH-box helicases in immunity, infection and cancers [PDF]

open access: yesCell Communication and Signaling
DEAD/DEAH-box helicases (DDX) are integral RNA-binding proteins within the RNA helicase superfamily 2 (SF2), characterized by distinct DEAD (Asp-Glu-Ala-Asp) and DEAH (Asp-Glu-Ala-His) motifs.

The expanding functions of cellular helicases: the tombusvirus RNA replication enhancer co-opts the plant eIF4AIII-like AtRH2 and the DDX5-like AtRH5 DEAD-box RNA helicases to promote viral asymmetric RNA replication.

open access: yesPLoS Pathogens, 2014
Replication of plus-strand RNA viruses depends on recruited host factors that aid several critical steps during replication. Several of the co-opted host factors bind to the viral RNA, which plays multiple roles, including mRNA function, as an assembly ...

RNA Silencing in the Antiviral Innate Immune Defence – Role of DEAD‐box RNA Helicases [PDF]

open access: yesScandinavian Journal of Immunology, 2010
AbstractRNA silencing is an efficient biochemical tool for gene knock downs as well as physiological phenomenon playing a major role in diverse biological processes. Recent knowledge suggests that the same protein families which mediate the experimental RNA interference (RNAi) in the fruit fly Drosophila melanogaster cells also contribute to the ...

The role of DEAD- and DExH-box RNA helicases in neurodevelopmental disorders [PDF]

open access: yesFrontiers in Molecular Neuroscience
Neurodevelopmental disorders (NDDs) represent a large group of disorders with an onset in the neonatal or early childhood period; NDDs include intellectual disability (ID), autism spectrum disorders (ASD), attention deficit hyperactivity disorders (ADHD),

Genera specific distribution of DEAD-box RNA helicases in cyanobacteria. [PDF]

open access: yesMicrob Genom, 2021
Although RNA helicases are essentially ubiquitous and perform roles in all stages of RNA metabolism, phylogenetic analysis of the DEAD (Asp-Glu-Ala-Asp)-box RNA helicase family in a single phylum has not been performed. Here, we performed a phylogenetic analysis on DEAD-box helicases from all currently available cyanobacterial genomes, comprising a ...

The emerging role of DEAD/H-box helicases in hepatitis B virus infection

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
DEAD/H-box helicases are an essential protein family with a conserved motif containing unique amino acid sequences (Asp-Glu-Ala-Asp/His). Current evidence indicates that DEAD/H-box helicases regulate RNA metabolism and innate immune responses.
