Molecular Interplay of PARN and Telomerase: Tail Modifiers and Disease Implications. [PDF]
Schematic representation of the molecular interplay between PARN, telomerase‐associated, and the involvement of p53 in regulating telomere maintenance and genome stability. The top panel shows how normal PARN levels are involved in regulating p53 levels and balanced telomerase activity through their regulatory interaction with TERC and TERRA, thus ...

Summary: Without new transcription, gene expression across the oocyte-to-embryo transition (OET) relies instead on regulation of mRNA poly(A) tails to control translation.

MARTRE family proteins negatively regulate CCR4-NOT activity to protect poly(A) tail length and promote translation of maternal mRNA [PDF]
The mammalian early embryo development requires translation of maternal mRNA inherited from the oocyte. While poly(A) tail length influences mRNA translation efficiency during the oocyte-to-embryo transition (OET), molecular mechanisms regulating ...

Rapid nuclear deadenylation of mammalian messenger RNA
Summary: Poly(A) tails protect RNAs from degradation and their deadenylation rates determine RNA stability. Although poly(A) tails are generated in the nucleus, deadenylation of tails has mostly been investigated within the cytoplasm.

microRNA-mediated messenger RNA deadenylation contributes to translational repression in mammalian cells. [PDF]
Animal microRNAs (miRNAs) typically regulate gene expression by binding to partially complementary target sites in the 3' untranslated region (UTR) of messenger RNA (mRNA) reducing its translation and stability.

Interaction between NANOS2 and the CCR4-NOT deadenylation complex is essential for male germ cell development in mouse. [PDF]
Nanos is one of the evolutionarily conserved proteins implicated in germ cell development and we have previously shown that it interacts with the CCR4-NOT deadenylation complex leading to the suppression of specific RNAs. However, the molecular mechanism

The Regulatory Properties of the Ccr4–Not Complex
The mammalian Ccr4–Not complex, carbon catabolite repression 4 (Ccr4)-negative on TATA-less (Not), is a large, highly conserved, multifunctional assembly of proteins that acts at different cellular levels to regulate gene expression.

CUG-BP and 3'UTR sequences influence PARN-mediated deadenylation in mammalian cell extracts
Several mRNAs have been shown to exhibit distinct patterns of poly(A) shortening prior to their decay in vivo. In this study, we show that individual transcripts also demonstrate distinct patterns of deadenylation in in vitro systems derived from HeLa ...

CNOT1 regulates circadian behaviour through Per2 mRNA decay in a deadenylation-dependent manner
Circadian clocks are an endogenous internal timekeeping mechanism that drives the rhythmic expression of genes, controlling the 24 h oscillatory pattern in behaviour and physiology.

The Dynamic Poly(A) Tail Acts as a Signal Hub in mRNA Metabolism
In eukaryotes, mRNA metabolism requires a sophisticated signaling system. Recent studies have suggested that polyadenylate tail may play a vital role in such a system.
