The Protein Family of RNA Helicases
Critical Reviews in Biochemistry and Molecular Biology, 1998RNA helicases represent a large family of proteins that have been detected in almost all biological systems where RNA plays a central role. They are ubiquitously distributed over a wide range of organisms and are involved in nuclear and mitochondrial splicing processes, RNA editing, rRNA processing, translation initiation, nuclear mRNA export, and mRNA

RNA helicases: modulators of RNA structure
Trends in Cell Biology, 1994RNA molecules play an essential role in many cellular processes, often as components of ribonucleoprotein complexes. Like proteins, RNA molecules adopt sequence-specific secondary and tertiary structures that are essential for function; alteration of these structures therefore provides a means of regulating RNA function.

Functions and mechanisms of RNA helicases in plants
Journal of Experimental Botany, 2022AbstractRNA helicases (RHs) are a family of ubiquitous enzymes that alter RNA structures and remodel ribonucleoprotein complexes typically using energy from the hydrolysis of ATP. RHs are involved in various aspects of RNA processing and metabolism, exemplified by transcriptional regulation, pre-mRNA splicing, miRNA biogenesis, liquid–liquid phase ...

Trends in Biochemical Sciences, 2001
In eukaryotic cells, all aspects of cellular RNA metabolism require putative RNA helicases of the DEAD and DExH protein families (collectively known as DExD/H families). Based on data from biochemical studies of a few of these RNA helicases, they are generally considered to be involved in the unwinding of duplex RNA molecules.

FEBS Journal, 2007 RNA helicases mediate structural rearrangements of RNA or RNA–protein complexes at the expense of ATP hydrolysis. Members of the DEAD box helicase family consist of two flexibly connected helicase domains. They share nine conserved sequence motifs that

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 ...

RNA helicases: regulators of differentiation
Clinical Biochemistry, 2005RNA helicases are highly conserved enzymes that utilize the energy derived from NTP hydrolysis to modulate the structure of RNA. RNA helicases participate in all biological processes that involve RNA, including transcription, splicing and translation. Based on the sequence of the helicase domain, they are classified into families, such as DDX and DHX ...

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).

Plant RNA helicases: linking aberrant and silencing RNA
Trends in Plant Science, 2009RNA helicases are ATPases that are capable of rearranging RNA and ribonucleoprotein (RNP) structure, and they can potentially function in any aspect of RNA metabolism. The RNA helicase gene family of plant genomes is larger and more diverse than genome families observed in other systems and provides an ideal model for investigation of the physiological

RNA helicases and RNA helicase-like proteins are the largest group of enzymes in eukaryotic RNA metabolism and although they are subject to intense ongoing research there is much confusion about function and classification of these enzymes. Although these enzymes are essential for virtually all processes involving RNA, there is no overview detailing ...
