Multifunctional roles of the mammalian CCR4-NOT complex in physiological phenomena
The CCR4-NOT complex serves as one of the major deadenylases of eukaryotes. Although it was originally identified and characterized in yeast, recent studies have revealed that the CCR4-NOT complex also exerts important functions in mammals, including ...

Chicken Pulmonary MicroRNAs Targeting the PB2 (Segment 1) of Avian Influenza Virus
The PB2 segment of H5N1 is essential for replication and host adaptation. We screened 200 miRNAs and identified five (gga‐miR‐17‐3p, gga‐miR‐29a‐5p, gga‐miR‐1718, gga‐miR‐16c‐5p, and gga‐miR‐1744‐5p) using thermodynamic stability of heteroduplex, seed sequence complementarity, conservation, and accessibility, offering insights into host antiviral ...

RNF219 attenuates global mRNA decay through inhibition of CCR4-NOT complex-mediated deadenylation
The CCR4-NOT complex is a key regulator of eukaryotic mRNA deadenylation. Here the authors identified the E3 ubiquitin ligase RNF219 as an acetylation-regulated cofactor of the complex, which inhibits mRNA decay through a direct interaction with NOT9.

SMG5-SMG7 authorize nonsense-mediated mRNA decay by enabling SMG6 endonucleolytic activity
Degradation of nonsense mediated mRNA decay (NMD) substrates is carried out by two seemingly independent pathways, SMG6-mediated endonucleolytic cleavage and/or SMG5-SMG7-induced accelerated deadenylation.

PABPC1 in Cancer: From a Translational Housekeeper to a Stress‐Responsive Regulatory Hub
PABPC1 shifts from a translational housekeeper to a stress‐responsive oncogenic hub via phase separation, PTMs, and non‐coding RNA crosstalk, selectively driving oncogene translation and therapy resistance in cancer. ABSTRACT PABPC1, long recognized as a constitutive translational housekeeper, has emerged as a stress‐responsive translational ...

Composition and function of P bodies in Arabidopsis thaliana
mRNA accumulation is tightly regulated by diverse molecular pathways. The identification and characterization of enzymes and regulatory proteins involved in controlling the fate of mRNA offers the possibility to broaden our understanding of ...

In acute brain injury (TBI/ICH), sympathetic hyperactivity is driven by hypothalamic FTO upregulation. FTO demethylates Trhr, blocking m6A‐YTHDF2‐dependent degradation, which stabilizes Trhr mRNA and increases neuronal sensitivity to TRH. Restoring FTO or Trhr alleviates sympathetic hyperactivity, offering a potential target for managing autonomic ...

Maternal mRNA deadenylation is defective in in vitro matured mouse and human oocytes
Oocyte in vitro maturation is a technique in assisted reproductive technology. Thousands of genes show abnormally high expression in in vitro maturated metaphase II (MII) oocytes compared to those matured in vivo in bovines, mice, and humans.

Circular Photocaged mRNA for Light‐induced Late‐stage Activation of Translation
A clickable photo‐caged 5′ cap (CyCliCap) allows to make Cyclic Click Cap‐containing mRNA (CyCliCap‐mRNA) which is remarkably stable and translationally muted until irradiated, allowing for late‐stage activation of translation in cells by light. ABSTRACT mRNA is a new medical modality as vaccine and raises hopes to become a protein replacement agent ...

CAF1 plays an important role in mRNA deadenylation separate from its contact to CCR4 [PDF]
The CAF1 protein is a component of the CCR4 - NOT deadenylase complex. While yeast CAF1 displays deadenylase activity, this activity is not required for its deadenylation function in vivo, and CCR4 is the primary deadenylase in the complex.
