The roles of the exoribonucleases DIS3L2 and XRN1 in disease [PDF]
RNA degradation is a vital post-transcriptional process which ensures that transcripts are maintained at the correct level within the cell. DIS3L2 and XRN1 are conserved exoribonucleases which are critical for the degradation of cytoplasmic RNAs ...

Investigating the correlation between Xrn1-resistant RNAs and frameshifter pseudoknots
Xrn1-resistant RNA structures are multifunctional elements employed by an increasing number of RNA viruses. One of such elements is the coremin motif, discovered in plant virus RNAs, of which the structure has been hypothesized to form a yet unelucidated

Cytoplasmic 5’-3’ exonuclease Xrn1p is also a genome-wide transcription factor in yeast [PDF]
The 5’ to 3’ exoribonuclease Xrn1 is a large protein involved in cytoplasmatic mRNA degradation as a critical component of the major decaysome. Its deletion in the yeast Saccharomyces cerevisiae is not lethal, but it has multiple physiological effects ...

Xrn1 Exoribonuclease—An Intrinsic Marker of Yeast Population Growth
Background: Xrn1 exoribonuclease is the major mRNA degradation enzyme in Saccharomyces cerevisiae. In exponentially growing cells, Xrn1 is localised in the yeast cells and directs the degradation of mRNA molecules.

The mRNA degradation factor Xrn1 regulates transcription elongation in parallel to Ccr4 [PDF]
Co-transcriptional imprinting of mRNA by Rpb4 and Rpb7 subunits of RNA polymerase II (RNAPII) and by the Ccr4–Not complex conditions its posttranscriptional fate.

The Yeast DNA Damage Checkpoint Kinase Rad53 Targets the Exoribonuclease, Xrn1 [PDF]
The highly conserved DNA damage response (DDR) pathway monitors the genomic integrity of the cell and protects against genotoxic stresses. The apical kinases, Mec1 and Tel1 (ATR and ATM in human, respectively), initiate the DNA damage signaling cascade ...

XRN1 Is a Species-Specific Virus Restriction Factor in Yeasts.
In eukaryotes, the degradation of cellular mRNAs is accomplished by Xrn1 and the cytoplasmic exosome. Because viral RNAs often lack canonical caps or poly-A tails, they can also be vulnerable to degradation by these host exonucleases.

Interrogating the degradation pathways of unstable mRNAs with XRN1-resistant sequences [PDF]
Degradation of messenger RNA is a key regulatory step in controlling eukaryotic gene expression. Here the authors present xrFrag, a molecular tool to interrogate the extent and directionality of mRNA turnover by the detection of stabilized decay ...
