Crystal structure and functional properties of the human CCR4-CAF1 deadenylase complex [PDF]
Nucleic Acids Research, 2021 Abstract The CCR4 and CAF1 deadenylases physically interact to form the CCR4-CAF1 complex and function as the catalytic core of the larger CCR4-NOT complex. Together, they are responsible for the eventual removal of the 3′-poly(A) tail from essentially all cellular mRNAs and consequently play a central role in the posttranscriptional ...

USB1 Is a miRNA Deadenylase That Regulates Hematopoietic Development
Blood, 2021 Abstract Poikiloderma with neutropenia (PN)is an autosomal-recessive bone marrow failure (BMF) syndrome in which patients harbor homozygous or compound heterozygous mutations in the human gene C16orf57, which encodes the evolutionarily conserved RNA 3' to 5' exonuclease U6 biogenesis 1 (USB1).

Global view on the metabolism of RNA poly(A) tails in yeast Saccharomyces cerevisiae
Nature Communications, 2021 RNA polyadenosine tails are important for the export, translation and stability of mRNAs and play a role in non-coding RNA biogenesis. Here the authors measure yeast poly(A) tail lengths by direct RNA sequencing, revealing its dynamics in yeast ...

GW182 Proteins Directly Recruit Cytoplasmic Deadenylase Complexes to miRNA Targets [PDF]
Molecular Cell, 2011 miRNAs are posttranscriptional regulators of gene expression that associate with Argonaute and GW182 proteins to repress translation and/or promote mRNA degradation. miRNA-mediated mRNA degradation is initiated by deadenylation, although it is not known whether deadenylases are recruited to the mRNA target directly or by default, as a consequence of a ...

Diverse Strategies Used by Picornaviruses to Escape Host RNA Decay Pathways
Viruses, 2016 To successfully replicate, viruses protect their genomic material from degradation by the host cell. RNA viruses must contend with numerous destabilizing host cell processes including mRNA decay pathways and viral RNA (vRNA) degradation resulting from ...

Human Pumilio Proteins Recruit Multiple Deadenylases to Efficiently Repress Messenger RNAs [PDF]
Journal of Biological Chemistry, 2012 PUF proteins are a conserved family of eukaryotic RNA-binding proteins that regulate specific mRNAs: they control many processes including stem cell proliferation, fertility, and memory formation. PUFs repress protein expression from their target mRNAs but the mechanism by which they do so remains unclear, especially for humans.

The deadenylase components Not2p, Not3p, and Not5p promote mRNA decapping [PDF]
RNA, 2016 Decay of mRNA is essential for the efficient regulation of gene expression. A major pathway of mRNA degradation is initiated by the shortening of the poly(A) tail via the CCR4/NOT deadenylase complex. Deadenylation is followed by removal of the 5′ cap (i.e., decapping) and then 5′ to 3′ exonucleolytic decay of the message body.

Nucleolin phosphorylation regulates PARN deadenylase activity during cellular stress response [PDF]
RNA Biology, 2017 Nucleolin (NCL) is an abundant stress-responsive, RNA-binding phosphoprotein that controls gene expression by regulating either mRNA stability and/or translation. NCL binds to the AU-rich element (ARE) in the 3'UTR of target mRNAs, mediates miRNA functions in the nearby target sequences, and regulates mRNA deadenylation. However, the mechanism by which

FEBS Open Bio, 2019 In eukaryotic cells, cytoplasmic mRNA is characterised by a 3′ poly(A) tail. The shortening and removal of poly(A) tails (deadenylation) by the Ccr4‐Not nuclease complex leads to reduced translational efficiency and RNA degradation.
