The Dynamic Poly(A) Tail Acts as a Signal Hub in mRNA Metabolism

open access: yesCells, 2023
In eukaryotes, mRNA metabolism requires a sophisticated signaling system. Recent studies have suggested that polyadenylate tail may play a vital role in such a system.

The role of TNRC6 proteins in gene silencing [PDF]

open access: yes, 2013
Proteins of the GW182 family have recently emerged as key players in miRNAmediated gene silencing. They have been shown to interact with Argonaute proteins, components of the RISC and are assumed to mediate the repression in metazoa. Three paralogues are

Cap‐dependent deadenylation of mRNA [PDF]

open access: yesThe EMBO Journal, 2000
Poly(A) tail removal is often the initial and rate-limiting step in mRNA decay and is also responsible for translational silencing of maternal mRNAs during oocyte maturation and early development. Here we report that deadenylation in HeLa cell extracts and by a purified mammalian poly(A)-specific exoribonuclease, PARN (previously designated ...

Deadenylation and P-Bodies [PDF]

open access: yes, 2012
Deadenylation is the major step in triggering mRNA decay and results in mRNA translation inhibition in eukaryotic cells. Therefore, it is plausible that deadenylation also induces the mRNP remodeling required for formation of GW bodies or RNA processing bodies (P-bodies), which harbor translationally silenced mRNPs.

Deadenylation and mRNA decay in Saccharomyces cerevisiae

open access: yes, 2001
The process of mRNA turnover is a critical component of the regulation of gene expression. In the past few years, a discrete set of pathways for the degradation of polyadenylated mRNAs, in eukaryotic cells have been described.

RGS16 Aggravates Hepatic Ischemia-Reperfusion Injury via Hepatocyte-Intrinsic Apoptosis/Inflammation & Neutrophil Recruitment/NETosis. [PDF]

open access: yesAdv Sci (Weinh)
RGS16 competitively interferes with the YTHDF3–PAN3 complex to prevent CXCL1 mRNA decay during hepatic ischemia‐reperfusion injury. Stabilized CXCL1 strengthens hepatocyte injury, neutrophil recruitment, and NET‐associated inflammation, uncovering how stress‐induced RGS16 converts post‐transcriptional regulation into immune‐mediated liver damage ...

MicroRNAs direct rapid deadenylation of mRNA [PDF]

open access: yesProceedings of the National Academy of Sciences, 2006
MicroRNAs (miRNAs) are ubiquitous regulators of eukaryotic gene expression. In addition to repressing translation, miRNAs can down-regulate the concentration of mRNAs that contain elements to which they are imperfectly complementary. Using miR-125b and let-7 as representative miRNAs, we show that in mammalian cells this reduction in message abundance ...

CNOT1 regulates circadian behaviour through Per2 mRNA decay in a deadenylation-dependent manner

open access: yesRNA Biology, 2022
Circadian clocks are an endogenous internal timekeeping mechanism that drives the rhythmic expression of genes, controlling the 24 h oscillatory pattern in behaviour and physiology.

Single molecule poly(A) tail-seq shows LARP4 opposes deadenylation throughout mRNA lifespan with most impact on short tails

open access: yeseLife, 2020
La-related protein 4 (LARP4) directly binds both poly(A) and poly(A)-binding protein (PABP). LARP4 was shown to promote poly(A) tail (PAT) lengthening and stabilization of individual mRNAs presumably by protection from deadenylation (Mattijssen et al ...

The BTG4 and CAF1 complex prevents the spontaneous activation of eggs by deadenylating maternal mRNAs [PDF]

open access: yesOpen Biology, 2016
Once every menstrual cycle, eggs are ovulated into the oviduct where they await fertilization. The ovulated eggs are arrested in metaphase of the second meiotic division, and only complete meiosis upon fertilization. It is crucial that the maintenance of
