Today's holiday ☕ reading is this 2024 paper on PARIS, a bacterial defense system shaped like a literal propeller that responds to viral infection by hitting the cellular self-destruct button - cleaving an essential tRNA. www.nature.com/articles/s41...
A virally encoded tRNA neutralizes the PARIS antiviral defence system - Nature
Structural and functional studies reveal how viral proteins trigger the phage antirestriction induced system (PARIS) to degrade host tRNA and how viral tRNAs suppress the PARIS nuclease and thereby ov...

We designed MS2 and PP7 binding coat proteins that are degraded in cells except when bound by their hairpin RNAs.

I’m thrilled to share a collaborative story from @Mendell_lab and Jan Erzberger labs, led by postdoc extraordinaire Xiaoqiang Zhu. We showed that in addition to their canonical decoding function, tRNAs play a key role in regulating mRNA stability during translation!

Specific tRNAs promote mRNA decay by recruiting the CCR4-NOT complex to translating ribosomes
The CCR4-NOT complex is a major regulator of eukaryotic messenger RNA (mRNA) stability. Slow decoding during translation promotes association of CCR4-NOT with ribosomes, accelerating mRNA degradation....
