curledEncodes the Drosophila Homolog of the Vertebrate Circadian Deadenylase Nocturnin [PDF]
AbstractDrosophila melanogaster curled, one of the first fly mutants described by T. H. Morgan >90 years ago, is the founding member of a series of curled wing phenotype mutants widely used as markers in fruit fly genetics. The expressivity of the wing phenotype is environmentally modulated, suggesting that the mutation affects the metabolic ...

The YTHDF family of proteins are able to bind and regulate the stability of methylated N6 RNA. Here the authors show that this decreased m6A RNA stability is mediated by direct recruitment of the CCR4–NOT deadenylase complex through YTHDF proteins.

The Not4 E3 ligase and CCR4 deadenylase play distinct roles in protein quality control. [PDF]
Eukaryotic cells control their proteome by regulating protein production and protein clearance. Protein production is determined to a large extent by mRNA levels, whereas protein degradation depends mostly upon the proteasome.

This graphical abstract illustrates the essential role of USB1 in neutrophil maturation. In normal myeloid cells, USB1 acts as an RNA exonuclease, trimming RNA tails to maintain proper RNA network function, which supports the differentiation of myeloid progenitor cells into mature neutrophils.

Mouse CAF1 Can Function As a Processive Deadenylase/3′–5′-Exonuclease in Vitro but in Yeast the Deadenylase Function of CAF1 Is Not Required for mRNA Poly(A) Removal [PDF]
The mouse CAF1 (mCAF1) is an ortholog of the yeast (y) CAF1 protein, which is a component of the CCR4-NOT complex, the major cytoplasmic deadenylase of Saccharomyces cerevisiae. Although CAF1 protein belongs to the DEDDh family of RNases, CCR4 appears to be the principle deadenylase of the CCR4-NOT complex.

Enhanced Intracellular Stability and Translation Efficiency of mRNA Drugs by a 2‐arm mRNA Platform
We constructed a 2‐arm mRNA, characterized by a unique topology formed through the dimerization of two mRNA 3’ tails. The 2‐arm mRNA improves 3’ tail stability and resistance to nuclease degradation, resulting in an intracellular half‐life of up to 65 h. This method substantially enhances the translation capacity of mRNA drugs.

Interaction of antiproliferative protein Tob with the CCR4‐NOT deadenylase complex
Tob protein, when overexpressed, suppresses growth of NIH3T3 cells, presumably by regulating expression of various growth‐related genes. However, the molecular mechanisms underlying Tob‐mediated regulation of gene expression have been obscure. To address this issue we established stable Tob‐expressing cell lines and used a proteomics approach to ...

The deadenylase components Not2p, Not3p, and Not5p promote mRNA decapping [PDF]
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.

CUG-BP binds to RNA substrates and recruits PARN deadenylase [PDF]
CUG-BP is the human homolog of the Xenopus EDEN-BP, which was shown previously to bind to mRNAs, such as c-mos, that exhibit rapid deadenylation following fertilization of the oocyte. While several studies have focused on roles of CUG-BP as a splicing or translation regulator in mammalian cells, its role in mRNA decay has not been examined in detail ...

Roquin proteins downregulate target mRNA expression by recruiting effectors such as the CCR4-NOT deadenylase complex. Here the authors provide molecular details of how Roquin proteins recruit the CCR4-NOT complex to repress the expression of its targets.
