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.

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 ...

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.

Role of Ccr4-Not complex in heterochromatin formation at meiotic genes and subtelomeres in fission yeast. [PDF]
, 2015 BACKGROUND: Heterochromatin is essential for chromosome segregation, gene silencing and genome integrity. The fission yeast Schizosaccharomyces pombe contains heterochromatin at centromeres, subtelomeres, and mating type genes, as well as at small ...

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.

HELZ directly interacts with CCR4–NOT and causes decay of bound mRNAs
Life Science Alliance, 2019 The putative UPF1-like SF1 helicase HELZ directly interacts with the CCR4–NOT deadenylase complex to induce translational repression and 5′-to-3′ decay of bound mRNAs. Eukaryotic superfamily (SF) 1 helicases have been implicated in various aspects of RNA

miRNAs as Influencers of Cell-Cell Communication in Tumor Microenvironment [PDF]
, 2020 microRNAs (miRNAs) are small noncoding RNAs that regulate gene expression at the posttranscriptional level, inducing the degradation of the target mRNA or translational repression.

Role of Cnot6l in maternal mRNA turnover
Life Science Alliance, 2018 Mice lacking Cnot6l , a deadenylase component of the CCR4–NOT complex, are viable, but females have ∼40% smaller litters. Cnot6l is a maternal-effect gene acting in maternal mRNA degradation.

The translational repressors Nanos and Pumilio have divergent effects on presynaptic terminal growth and postsynaptic glutamate receptor subunit composition [PDF]
, 2009 Pumilio (Pum) is a translational repressor that binds selectively to target mRNAs and recruits Nanos (Nos) as a corepressor. In the larval neuromuscular system, Pum represses expression of the translation factor eIF-4E and the glutamate receptor subunit ...
