Mtr4 RNA helicase structures and interactions
Biological Chemistry, 2021 Abstract Mtr4 is a Ski2-like RNA helicase that plays a central role in RNA surveillance and degradation pathways as an activator of the RNA exosome. Multiple crystallographic and cryo-EM studies over the past 10 years have revealed important insight into the Mtr4 structure and interactions with protein and nucleic acid binding partners ...

Identification and functional analysis of novel phosphorylation sites in the RNA surveillance protein Upf1. [PDF]
, 2013 One third of inherited genetic diseases are caused by mRNAs harboring premature termination codons as a result of nonsense mutations. These aberrant mRNAs are degraded by the Nonsense-Mediated mRNA Decay (NMD) pathway.

Roles of the linker region of RNA helicase A in HIV-1 RNA metabolism. [PDF]
PLoS ONE, 2013 RNA helicase A (RHA) promotes multiple steps in HIV-1 production including transcription and translation of viral RNA, annealing of primer tRNA(Lys3) to viral RNA, and elevating the ratio of unspliced to spliced viral RNA.

To translate, or not to translate: viral and host mRNA regulation by interferon-stimulated genes. [PDF]
, 2015 Type I interferon (IFN) is one of the first lines of cellular defense against viral pathogens. As a result of IFN signaling, a wide array of IFN-stimulated gene (ISG) products is upregulated to target different stages of the viral life cycle.

Molecular characterization of DDX26, a human DEAD-box RNA helicase, located on chromosome 7p12
Brazilian Journal of Medical and Biological Research, 2001 DEAD-box proteins comprise a family of ATP-dependent RNA helicases involved in several aspects of RNA metabolism. Here we report the characterization of the human DEAD-box RNA helicase DDX26. The gene is composed of 14 exons distributed over an extension
