The RNA exosome complex constitutes the major nuclear eukaryotic 3′-5′ exonuclease. Outside of nucleoli, the human nucleoplasmic exosome is directed to some of its substrates by the nuclear exosome targeting (NEXT) complex.

Sphingolipids in the trans-Golgi network have been implicated in polar trafficking. Here Wattelet-Boyer et al. show that hydroxylated C24- and C26-acyl-chain sphingolipids are enriched in trans-Golgi network subdomains that are critical for polar sorting

Disruption of ribosome biogenesis triggers a p21/p53-mediated cell cycle checkpoint [PDF]
Cell cycle entry requires a dramatic increase in protein production. In order to cope with this demand, the cell must upregulate ribosome biogenesis. Given that ribosome biogenesis is the most energy-consuming anabolic process in a growing cell, and ...

Lipids or Proteins: Who Is Leading the Dance at Membrane Contact Sites?
Understanding the mode of action of membrane contact sites (MCSs) across eukaryotic organisms at the near-atomic level to infer function at the cellular and tissue levels is a challenge scientists are currently facing. These peculiar systems dedicated to

Molecular genetic analysis of siRNA biogenesis and function in Arabidopsis thaliana [PDF]
In diverse eukaryotes, small RNA products of Dicer-like (DCL) proteins regulate mRNA stability or translation, and direct chromatin modifications to genomic regions, phenomena collectively known as RNA silencing.
