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

Deadenylation—a piece of PANcake [PDF]

open access: yesThe EMBO Journal, 2014
Pan is a poly(A)‐specific 3′ exoribonuclease that, together with the CCR4‐NOT complex, is responsible for initiating and controlling mRNA decay by degradation of the poly(A) tail. Now, more than twenty years after the enzyme's discovery, a surge of recent papers, including one in this issue of The EMBO Journal (Wolf et al, ) has revealed details of its

Rous Sarcoma Virus RNA Stability Element Inhibits Deadenylation of mRNAs with Long 3′UTRs

open access: yesViruses, 2017
All retroviruses use their full-length primary transcript as the major mRNA for Group-specific antigen (Gag) capsid proteins. This results in a long 3′ untranslated region (UTR) downstream of the termination codon. In the case of Rous sarcoma virus (RSV),

Traffic into silence: endomembranes and post-transcriptional RNA silencing. [PDF]

open access: yes, 2014
microRNAs (miRNAs) and small interfering RNAs (siRNAs) are small RNAs that repress gene expression at the post-transcriptional level in plants and animals. Small RNAs guide Argonaute-containing RNA-induced silencing complexes to target RNAs in a sequence-

Deadenylation of mRNA by the CCR4-NOT complex in Drosophila: molecular and developmental aspects

open access: yesFrontiers in Genetics, 2014
Controlled shortening of the poly(A) tail of mRNAs is the first step in eukaryotic mRNA decay and can also be used for translational inactivation of mRNAs.

Translation Efficiency and Degradation of ER-Associated mRNAs Modulated by ER-Anchored poly(A)-Specific Ribonuclease (PARN)

open access: yesCells, 2020
Translation is spatiotemporally regulated and endoplasmic reticulum (ER)-associated mRNAs are generally in efficient translation. It is unclear whether the ER-associated mRNAs are deadenylated or degraded on the ER surface in situ or in the cytosol. Here,

Molecular Insights into mRNA Polyadenylation and Deadenylation

open access: yesInternational Journal of Molecular Sciences, 2022
Poly(A) tails are present on almost all eukaryotic mRNAs, and play critical roles in mRNA stability, nuclear export, and translation efficiency. The biosynthesis and shortening of a poly(A) tail are regulated by large multiprotein complexes. However, the molecular mechanisms of these protein machineries still remain unclear.

HPat a decapping activator interacting with the miRNA effector complex.

open access: yesPLoS ONE, 2013
Animal miRNAs commonly mediate mRNA degradation and/or translational repression by binding to their target mRNAs. Key factors for miRNA-mediated mRNA degradation are the components of the miRNA effector complex (AGO1 and GW182) and the general mRNA ...

Mitochondrial dysfunction reveals the role of mRNA poly(A) tail regulation in oculopharyngeal muscular dystrophy pathogenesis. [PDF]

open access: yesPLoS Genetics, 2015
Oculopharyngeal muscular dystrophy (OPMD), a late-onset disorder characterized by progressive degeneration of specific muscles, results from the extension of a polyalanine tract in poly(A) binding protein nuclear 1 (PABPN1).

RNA binding protein AUF1/HNRNPD regulates nuclear export, stability and translation of SNCA transcripts

open access: yesOpen Biology, 2023
Alpha-synuclein (SNCA) accumulation plays a central role in the pathogenesis of Parkinson's disease. Determining and interfering with the mechanisms that control SNCA expression is one approach to limiting disease progression.
