How do cells sort which RNAs to keep or destroy? New preprint from THJ, Brenneke and Plaschka labs shows that export and decay machineries (TREX2/PAXT) both recognise UAP56-bound RNAs. Whether they’re exported or degraded depends on where in the nucleus this happens.

Eukaryotic genomes generate a plethora of polyadenylated (pA+) RNAs, that are packaged into ribonucleoprotein particles (RNPs). To ensure faithful gene expression, functional pA+ RNPs, including prote...
