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.

A helicase links upstream ORFs and RNA structure [PDF]
Current Genetics, 2018 Upstream open reading frames (uORFs) in 5' UTRs of eukaryotic mRNAs are increasingly recognized as important elements that regulate cellular protein synthesis. Since uORFs can start from non-AUG codons, an enormous number of potential uORF initiation sites exists in 5'UTRs.

Recognition of two distinct elements in the RNA substrate by the RNA-binding domain of the T. thermophilus DEAD box helicase Hera [PDF]
, 2013 DEAD box helicases catalyze the ATP-dependent destabilization of RNA duplexes. Whereas duplex separation is mediated by the helicase core shared by all members of the family, flanking domains often contribute to binding of the RNA substrate.

Helicase: A genetic tool for providing stress tolerance in plants
Plant Stress, 2023 Alteration of stress (abiotic and biotic) constitutes one of the major problems for normal plants health. In the present scenario, new molecular tools are broadly utilized to improve stress tolerance and high-yielding crop plants.

Targeting the eIF4A RNA helicase blocks translation of the MUC1-C oncoprotein [PDF]
, 2012 The oncogenic MUC1-C subunit is aberrantly overexpressed in most human breast cancers by mechanisms that are not well understood. The present studies demonstrate that stimulation of non- malignant MCF-10A cells with epidermal growth factor (EGF) or ...

Methotrexate, an anti-inflammatory drug, inhibits Hepatitis E viral replication
Journal of Enzyme Inhibition and Medicinal Chemistry, 2023 Hepatitis E Virus (HEV) is a positively oriented RNA virus having a 7.2 kb genome. HEV consists of three open reading frames (ORF1-3). Of these, ORF1 codes for the enzymes Methyltransferase (Mtase), Papain-like cysteine protease (PCP), RNA helicase, and ...

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

PLoS Pathogens, 2020 Positive-stranded (+)RNA viruses greatly exploit host cells to support viral replication. However, unlike many other pathogens, (+)RNA viruses code for only a limited number of genes, making them highly dependent on numerous co-opted host factors for ...

RNA helicase A modulates translation of HIV-1 and infectivity of progeny virions
Nucleic Acids Research, 2009 Retroviruses rely on host RNA-binding proteins to modulate various steps in their replication. Previously several animal retroviruses were determined to mediate Dhx9/RNA helicase A (RHA) interaction with a 5′ terminal post-transcriptional control element
