RNA helicase DDX21 coordinates transcription and ribosomal RNA processing [PDF]
Nature, 2014 DEAD-box RNA helicases are vital for the regulation of various aspects of the RNA life cycle, but the molecular underpinnings of their involvement, particularly in mammalian cells, remain poorly understood. Here we show that the DEAD-box RNA helicase DDX21 can sense the transcriptional status of both RNA polymerase (Pol) I and II to control multiple ...

Role and therapeutic potential of DEAD-box RNA helicase family in colorectal cancer
Frontiers in Oncology, 2023 Colorectal cancer (CRC) is the third most commonly diagnosed and the second cancer-related death worldwide, leading to more than 0.9 million deaths every year. Unfortunately, this disease is changing rapidly to a younger age, and in a more advanced stage

The RNA helicase database [PDF]
Nucleic Acids Research, 2010 RNA helicases are ubiquitous and essential enzymes that function in nearly all aspects of RNA metabolism. The RNA helicase database (www.rnahelicase.org) integrates the wealth of accumulating information on RNA helicases in a readily accessible format.

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.

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 ...

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 ...

LGP2 plays a critical role in sensitizing mda-5 to activation by double-stranded RNA. [PDF]
, 2013 The DExD/H box RNA helicases retinoic acid-inducible gene-I (RIG-I) and melanoma differentiation associated gene-5 (mda-5) sense viral RNA in the cytoplasm of infected cells and activate signal transduction pathways that trigger the production of type I ...
