Helicase associated 2 domain is essential for helicase activity of RNA helicase A
Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2014RNA helicase A (RHA), a DExD/H box protein, plays critical roles in a wide variety of cellular or viral functions. RHA contains a conserved core helicase domain that is flanked by five other domains. Two double-stranded RNA binding domains (dsRBD1 and dsRBD2) are at the N-terminus, whereas HA2 (helicase associated 2), OB-fold (oligonucleotide- or ...

Nucleolar localization of murine nuclear DNA helicase II (RNA helicase A)
Journal of Cell Science, 1999ABSTRACT Nuclear DNA helicase II (NDH II) is a highly conserved member of the DEXH superfamily of eukaryotic helicases, whose physiological role is still unclear. To explore the function of NDH II, we studied the intracellular distribution of NDH II of different mammalian species by immunofluorescence and compared these findings with the

Molecular Characterization of Nuclear DNA Helicase II (RNA Helicase A)
2009Nuclear DNA helicase II (NDH II) was first isolated from calf thymus using a DNA-unwinding assay. Subsequently it has been shown to be a homologue of human RNA helicase A (RHA) and the maleless protein (MLE) from Drosophila. Accordingly, the protein possesses both DNA and RNA unwinding activities.

A DEAD-box RNA helicase in the Escherichia coli RNA degradosome
Nature, 1996The Escherichia coli RNA degradosome is a multi-enzyme complex that contains the exoribonuclease polynucleotide phosphorylase (PNPase) and the endoribonuclease RNase E. Both enzymes are important in RNA processing and messenger RNA degradation. Here we report that enolase and RhlB are two other major components of the degradosome.

RNA helicase A is necessary for translation of selected messenger RNAs
Nature Structural & Molecular Biology, 2006RNA helicase A (RHA) is a highly conserved DEAD-box protein that activates transcription, modulates RNA splicing and binds the nuclear pore complex. The life cycle of typical mRNA involves RNA processing and translation after ribosome scanning of a relatively unstructured 5' untranslated region (UTR).

CaRH57, a RNA helicase, contributes pepper tolerance to heat stress
Plant Physiology and Biochemistry, 2023RNA helicases (RHs) are required for most aspects of RNA metabolism and play an important role in plant stress tolerance. Heat stress (HS) causes the deleterious effects on plant cells, such as membrane disruption and protein misfolding, which results in the inhibition of plant growth and development.

The RNA helicase Mtr4p is a duplex-sensing translocase
Nature Chemical Biology, 2016The conserved Saccharomyces cerevisiae Ski2-like RNA helicase Mtr4p plays essential roles in eukaryotic nuclear RNA processing. RNA helicase activity of Mtr4p is critical for biological functions of the enzyme, but the molecular basis for RNA unwinding is not understood.

Molecular determinants of nucleolar translocation of RNA helicase A
Experimental Cell Research, 2007RNA helicase A (RHA) is a member of the DEAH-box family of DNA/RNA helicases involved in multiple cellular processes and the life cycles of many viruses. The subcellular localization of RHA is dynamic despite its steady-state concentration in the nucleoplasm.
