Domain orientation in the RNA helicase YxiN and the role of conformational changes for RNA unwinding [PDF]

open access: yes, 2010
The RNA helicase YxiN from Bacillus subtilis is a member of the family of DEAD box proteins. YxiN is able to unwind RNA double strands in an ATP-dependent manner. The ability to catalyse RNA rearrangement is in vivo presumably necessary for the bacterial

Recognition of two distinct elements in the RNA substrate by the RNA-binding domain of the T. thermophilus DEAD box helicase Hera [PDF]

open access: yes, 2013
DEAD box helicases catalyze the ATP-dependent destabilization of RNA duplexes. Whereas duplex separation is mediated by the helicase core shared by all members of the family, flanking domains often contribute to binding of the RNA substrate.

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.

Biological roles of DExH RNA helicase, RHAU [PDF]

open access: yes, 2007
In this thesis, I have described the work carried out on a single protein called RHAU, dealing with aspects of protein localization in cells, the regulation of global gene expression by different mechanisms, and cellular stress-responses.

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 ...

Paramyxovirus V proteins interact with the RNA helicase LGP2 to inhibit RIG-I-dependent interferon induction [PDF]

open access: yes, 2014
This work was supported by the Wellcome Trust (grant AL087751/B)RIG-I and mda-5 are activated by viral RNA and stimulate type I interferon production. Laboratory of genetics and physiology 2 (LGP2) shares homology with RIG-I and mda-5 but lacks the CARD ...

Methotrexate, an anti-inflammatory drug, inhibits Hepatitis E viral replication

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2023
Hepatitis E Virus (HEV) is a positively oriented RNA virus having a 7.2 kb genome. HEV consists of three open reading frames (ORF1-3). Of these, ORF1 codes for the enzymes Methyltransferase (Mtase), Papain-like cysteine protease (PCP), RNA helicase, and ...

Structural basis of Zika virus helicase in recognizing its substrates

open access: yesProtein & Cell, 2016
The recent explosive outbreak of Zika virus (ZIKV) infection has been reported in South and Central America and the Caribbean. Neonatal microcephaly associated with ZIKV infection has already caused a public health emergency of international concern.

Investigation of the guanine quadruplex resolving activity of the DEAH-box RNA helicase RHAU [PDF]

open access: yes, 2012
Generally depicted as single- or double-stranded molecules, nucleic acids sequences can adopt various forms of stable secondary structures. In particular, guanine-riche sequence of DNA and RNA can form atypical four-stranded helical structures termed G ...

Coordinated function of cellular DEAD-box helicases in suppression of viral RNA recombination and maintenance of viral genome integrity. [PDF]

open access: yesPLoS Pathogens, 2015
The intricate interactions between viruses and hosts include an evolutionary arms race and adaptation that is facilitated by the ability of RNA viruses to evolve rapidly due to high frequency mutations and genetic RNA recombination.
