Pumilio protects Xbp1 mRNA from regulated Ire1-dependent decay
In Drosophila, ER-targeted mRNAs are degraded by Ire1-dependent pathway. Here the authors report that the fly mRNA binding protein Pumilio is phosphorylated by Ire1 and binds to Xbp1 mRNA, protecting it from the non-canonical endoribonuclease activity of

Functional plasticity of antibacterial EndoU toxins. [PDF]
Bacteria use several different secretion systems to deliver toxic EndoU ribonucleases into neighboring cells. Here, we present the first structure of a prokaryotic EndoU toxin in complex with its cognate immunity protein.

Mechanistic understanding of human SLFN11
Schlafen 11 serves as an antiviral restriction factor and a predictive biomarker in cancer. Here, the authors use cryoelectron microscopy and biochemical assays to understand tRNA endoribonuclease and DNA binding functions of human Schlafen 11.

Tipiracil binds to uridine site and inhibits Nsp15 endoribonuclease NendoU from SARS-CoV-2
SARS-CoV-2 Nsp15 is a uridine-specific endoribonuclease with C-terminal catalytic domain belonging to the EndoU family that is highly conserved in coronaviruses.

Novel specificity of an endoribonuclease of yeast [PDF]
Investigations of the cleavage specificity of a cyclizing endoribonuclease of yeast show that it hydrolyzes Y‐A bonds of single‐stranded regions of RNA and that oligonucleotides are hydrolyzed poorly. The stringent specificity of the enzyme suggests that it may be useful for generating specific fragments of polyribonucleotides.

Nonstructural Protein 11 of Porcine Reproductive and Respiratory Syndrome Virus Suppresses Both MAVS and RIG-I Expression as One of the Mechanisms to Antagonize Type I Interferon Production. [PDF]
Type I interferons (IFN-α/β) play a key role in antiviral defense, and porcine reproductive and respiratory syndrome virus (PRRSV) is known to down-regulate the IFN response in virus-infected cells and pigs.
