, 2019 RNAs can be either transcribed directly as functional species or as molecules that require post-transcriptional processing by ribonucleases. Most messenger RNAs fall into the first category, while most structural RNAs fall into the second. There are, however, some specific examples of mRNAs that undergo processing to shorter, more stable species with a

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

RNA interference, growth and differentiation appear normal in African trypanosomes lacking Tudor staphylococcal nuclease. [PDF]
, 2010 Ribonucleases play important roles in the RNA interference (RNAi) pathway. The Dicer endonuclease converts double-stranded (ds)RNA into small interfering (si)RNA and the Slicer endonuclease, as a component of the RNA induced silencing complex (RISC ...

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

RNA Surveillance by the Nuclear RNA Exosome: Mechanisms and Significance
Non-Coding RNA, 2018 The nuclear RNA exosome is an essential and versatile machinery that regulates maturation and degradation of a huge plethora of RNA species. The past two decades have witnessed remarkable progress in understanding the whole picture of its RNA substrates ...

Rrp47p is an exosome-associated protein required for the 3 ' processing of stable RNAs [PDF]
, 2003 Related exosome complexes of 3'-->5' exonucleases are present in the nucleus and the cytoplasm. Purification of exosome complexes from whole-cell lysates identified a Mg2+-labile factor present in substoichiometric amounts. This protein was identified

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Characterization of factors involved in the coupling of 3' end processing and splicing and in the 3' end formation of mRNA precursors [PDF]
, 2006 Eukaryotic mRNA precursors are processed at their 5’ and 3’ ends and are spliced prior to their export from the nucleus to the cytoplasm. Although all three processing reactions can be studied separately in vitro, they are coupled in vivo.
