RNA helicases in bacteria [PDF]
Current Opinion in Microbiology, 2016 RNA plays a crucial role in the control of bacterial gene expression, either as carrier of information or as positive or negative regulators. Moreover, the machinery to decode the information, the ribosome, is a large ribonucleoprotein complex composed of rRNAs and many proteins.

Cytoplasmic ribonucleoprotein complexes, RNA helicases and coronavirus infection
Frontiers in Virology, 2022 RNA metabolism in the eukaryotic cell includes the formation of ribonucleoprotein complexes (RNPs) that, depending on their protein components, have a different function.

RNA remodeling by hexameric RNA helicases [PDF]
RNA Biology, 2010 The unwinding of RNA helices and the disruption of RNA-protein complexes are critical steps of cellular metabolism that are carried out by ubiquitous NTP-dependent enzymes named RNA helicases. Here, we review the structures, mechanisms, and biochemical properties of two RNA helicases known to adopt a homo-hexameric ring architecture: the P4 packaging ...

RNA Unwinding by the Trf4/Air2/Mtr4 Polyadenylation (TRAMP) Complex [PDF]
, 2012 Many RNA-processing events in the cell nucleus involve the Trf4/Air2/Mtr4 polyadenylation (TRAMP) complex, which contains the poly(A) polymerase Trf4p, the Zn-knuckle protein Air2p, and the RNA helicase Mtr4p.

Redox-Regulated RNA Helicase Expression [PDF]
Plant Physiology, 2000 Abstract In photosynthetic organisms it is becoming increasingly evident that light-driven shifts in redox potential act as a sensor that initiates alterations in gene expression at both the level of transcription and translation. This report provides evidence that the expression of a cyanobacterial RNA helicase gene,crhR, is controlled ...

The role of RNA helicases in aging and lifespan regulation
Translational Medicine of Aging, 2017 RNA helicases are members of a large family of enzymes that function in unwinding RNA duplexes and modulating interactions between RNAs and proteins. RNA helicases participate in numerous cellular processes, including transcription, translation, mRNA ...

psiCLIP reveals dynamic RNA binding by DEAH-box helicases before and after exon ligation
Nature Communications, 2021 ATP-dependent helicases remodel the spliceosome and proofread splice site recognition. A new method – Purified Spliceosome iCLIP (psiCLIP) – probes protein-RNA interactions in defined spliceosome complexes to reveal how the helicases Prp16 and Prp22 ...

Quantitative analysis of snoRNA association with pre-ribosomes and release of snR30 by Rok1 helicase [PDF]
, 2008 In yeast, three small nucleolar RNAs (snoRNAs) are essential for the processing of pre-ribosomal RNA—U3, U14 and snR30—whereas 72 non-essential snoRNAs direct site-specific modification of pre-rRNA. We applied a quantitative screen for alterations in the

Identification of Five Putative Yeast RNA Helicase Genes [PDF]
, 1990 The RNA helicase gene family encodes a group of eight homologous proteins that share regions of sequence similarity. This group of evolutionarily conserved proteins presumably all utilize ATP (or some other nucleoside triphosphate) as an energy source ...
