ARTICLE RST1 and RIPR connect the cytosolic RNA exosome to the Ski complex in Arabidopsis

Archive ouverte | Lange, Heike | CCSD

International audience. The RNA exosome is a key 3'−5' exoribonuclease with an evolutionarily conserved structure and function. Its cytosolic functions require the co-factors SKI7 and the Ski complex. Here we demons...

Molecular connection between the TUTase URT1 and decapping activators

Archive ouverte | Scheer, Hélène | CCSD

Uridylation is a widespread modification destabilizing eukaryotic mRNAs. Yet, molecular mechanisms underlying TUTase-mediated mRNA degradation remain mostly unresolved. Here, we report that the Arabidopsis TUTase URT1 participates...

The TUTase URT1 connects decapping activators and prevents the accumulation of excessively deadenylated mRNAs to avoid siRNA biogenesis
