The 5' → 3' exoribonuclease XRN1/Pacman and its functions in cellular processes and development [PDF]

open access: yes, 2012
XRN1 is a 5' → 3' processive exoribonuclease that degrades mRNAs after they have been decapped. It is highly conserved in all eukaryotes, including homologs in Drosophila melanogaster (Pacman), Caenorhabditis elegans (XRN1), and Saccharomyces cerevisiae (

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

Post-transcriptional Stabilization of Ucp1 mRNA Protects Mice from Diet-Induced Obesity

open access: yesCell Reports, 2015
Uncoupling protein 1 (Ucp1) contributes to thermogenesis, and its expression is regulated at the transcriptional level. Here, we show that Ucp1 expression is also regulated post-transcriptionally.

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

Genome-wide profiling of uncapped mRNA [PDF]

open access: yes, 2012
Gene transcripts are under extensive posttranscriptional regulation, including the regulation of their stability. A major route for mRNA degradation produces uncapped mRNAs, which can be generated by decapping enzymes, endonucleases, and small RNAs ...

Dynamic Control of Dendritic mRNA Expression by CNOT7 Regulates Synaptic Efficacy and Higher Cognitive Function

open access: yesCell Reports, 2017
Translation of mRNAs in dendrites mediates synaptic plasticity, the probable cellular basis of learning and memory. Coordination of translational inhibitory and stimulatory mechanisms, as well as dendritic transport of mRNA, is necessary to ensure proper

SPT5 affects the rate of mRNA degradation and physically interacts with CCR4 but does not control mRNA deadenylation [PDF]

open access: yes, 2011
The CCR4-NOT complex has been shown to have multiple roles in mRNA metabolism, including that of transcriptional elongation, mRNA transport, and nuclear exosome function, but the primary function of CCR4 and CAF1 is in the deadenylation and degradation ...

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 ...

Insights into the structure and architecture of the CCR4-NOT complex

open access: yesFrontiers in Genetics, 2014
The CCR4-NOT complex is a highly conserved, multifunctional machinery with a general role in controlling mRNA metabolism. It has been implicated in a number of different aspects of mRNA and protein expression, including mRNA degradation, transcription ...
