RNA Catalysis as a Probe for Chaperone Activity of DEAD-Box Helicases [PDF]
, 2012 DEAD-box proteins are vitally important to cellular processes and make up the largest class of helicases. Many DEAD-box proteins function as RNA chaperones by accelerating structural transitions of RNA, which can result in the resolution of misfolded conformers or conversion between functional structures.

The RNA helicase Rm62 cooperates with SU(VAR)3-9 to re-silence active transcription in Drosophila melanogaster. [PDF]
, 2011 Gene expression is highly dynamic and many genes show a wide range in expression over several orders of magnitude. This regulation is often mediated by sequence specific transcription factors.

A Cytosine‑Bulged (3+1) Hybrid G‑Quadruplex Formed by the Chicken DNA Replication Origin
Chemistry – A European Journal, EarlyView.The first high‐resolution structure of an OGRE‐derived G‐quadruplex from the chicken β‐globin replication origin reveals an intramolecular three‐layer (3+1) hybrid fold with a cytosine bulge and an unprecedented 5'‐outer‐quartet anti guanine, creating a distinctive surface for molecular recognition.

Proteomic signatures of equine dental tooth tissues in ageing and disease
Equine Veterinary Journal, EarlyView.Abstract Background Ageing and dental disease in horses lead to structural and functional deterioration of dental tissues, yet their molecular signatures remain poorly characterised. Understanding how these processes alter the protein composition of enamel, dentin, cementum and pulp is essential for improving equine oral health and identifying ...

DEAD-Box RNA Helicases in Gram-Positive RNA Decay
, 2012 DEAD-box RNA helicases are important players in eukaryotic and bacterial RNA metabolism. A helicase from Staphylococcus aureus was recently shown to affect RNA decay, most likely via its interaction with the proposed Gram-positive degradosome. Some, but not all, RNAs are stabilized when the helicase CshA is mutated, and among the affected RNAs is the ...

iMeta, EarlyView.The Human Biomarker Navigator integrates the disease continuum, biomarker dynamics, cross‐organ biomarker networks, biomarker classification, and technology‐driven paradigms. It maps how biomarkers link multi‐system physiology and pathology across the nervous, respiratory, endocrine, circulatory, immune, digestive, urinary, reproductive, and ...

Journal of Clinical Laboratory Analysis, EarlyView.This study developed an optimized multiplex RT‐MIRA assay for the simultaneous detection of EML4‐ALK variants, achieving single‐copy sensitivity. Unexpectedly, during the development of the reaction system, we discovered a “low‐concentration enhancement effect,” where reducing primer or probe concentrations within a specific range markedly improved ...

The RNA helicase DDX3X is an essential mediator of innate antimicrobial immunity.
PLoS Pathogens, 2018 DExD/H box RNA helicases, such as the RIG-I-like receptors (RLR), are important components of the innate immune system. Here we demonstrate a pivotal and sex-specific role for the heterosomal isoforms of the DEAD box RNA helicase DDX3 in the immune ...

The Kaohsiung Journal of Medical Sciences, EarlyView.ABSTRACT Ultraviolet B (UVB) radiation is a major risk factor for cataract development, but the molecular mechanisms underlying this process, particularly the involvement of regulated cell death pathways such as ferroptosis, remain unclear. Transcriptomic, proteomic, and metabolomic analyses were performed on lens tissues from UVB‐induced cataract rat ...

A novel dimerization motif in the C-terminal domain of the Thermus thermophilus DEAD box helicase Hera confers substantial flexibility [PDF]
, 2008 DEAD box helicases are involved in nearly all aspects of RNA metabolism. They share a common helicase core, and may comprise additional domains that contribute to RNA binding. The Thermus thermophilus helicase Hera is the first dimeric DEAD box helicase.
