LGP2 plays a critical role in sensitizing mda-5 to activation by double-stranded RNA.

, 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 ...

RNA‐centric world of retroviruses: unravelling the molecular strategies of genomic RNA packaging

Biological Reviews, EarlyView.
ABSTRACT Retroviruses constitute a unique group of RNA viruses that have profoundly influenced both evolutionary trajectories and biomedical research. Their ability to reverse transcribe and integrate into host genomes has shaped genomic architecture across species and contributed to our understanding of oncogenes, gene regulation, and RNA biology ...

The newly discovered Q motif of DEAD‐box RNA helicases regulates RNA‐binding and helicase activity [PDF]

The EMBO Journal, 2004
DEAD-box proteins are the most common RNA helicases, and they are associated with virtually all processes involving RNA. They have nine conserved motifs that are required for ATP and RNA binding, and for linking phosphoanhydride cleavage of ATP with helicase activity.

Epigenetic Dysregulation of Somatostatin Receptors (SSTR) 1–5 and Therapeutic Implications in Neuroendocrine and Non‐Neuroendocrine Malignancies

International Journal of Cancer, EarlyView.
ABSTRACT Somatostatin receptors (SSTR) mediate the antiproliferative, antisecretory, and proapoptotic effects of somatostatin and its synthetic analogs. Their surface expression on neuroendocrine tumor (NET) cells is required for somatostatin analog therapy and radiopharmaceutical therapy (RPT).

Oncogenic KRAS Rewires Stress Granule Dynamics: Mechanisms and Therapeutic Opportunities

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Stress granules (SGs) are dynamic, membrane‐less structures that form in response to various cellular stresses, including metabolic, oxidative, and therapeutic challenges. They function as adaptive hubs and reorganize protein synthesis and signaling networks to help cells survive under stress. In cancer, these condensates are often hijacked to

The DEAD-box RNA helicase CrhB exhibits pleiotropic functions in the cyanobacterium Anabaena PCC 7120

Water Biology and Security
DEAD-box RNA helicases play critical roles in regulating RNA metabolism and gene expression in both prokaryotes and eukaryotes. In the filamentous, heterocyst-forming cyanobacterium Anabaena PCC 7120, two DEAD-box helicases, CrhB and CrhC, are present ...

The Sole DEAD-Box RNA Helicase of the Gastric Pathogen Helicobacter pylori Is Essential for Colonization

mBio, 2018
Present in every kingdom of life, generally in multiple copies, DEAD-box RNA helicases are specialized enzymes that unwind RNA secondary structures. They play major roles in mRNA decay, ribosome biogenesis, and adaptation to cold temperatures.

Conserved requirement for DEAD-box RNA helicase Gemin3 in Drosophila oogenesis [PDF]

BMC Research Notes, 2012
DEAD-box RNA helicase Gemin3 is an essential protein since its deficiency is lethal in both vertebrates and invertebrates. In addition to playing a role in transcriptional regulation and RNA silencing, as a core member of the SMN (survival of motor neurons) complex, Gemin3 is required for the biogenesis of spliceosomal snRNPs (small nuclear ...
