- Eukaryotic cells have evolved quality control mechanisms to degrade aberrant mRNA molecules and prevent the synthesis of defective proteins that could be deleterious for the cell. The exosome, a protein complex with ribonuclease activity, is a key player in quality control. An early quality checkpoi

- Upon nuclear export, RNP particles are either localized to polysomes or further assembled into larger RNA granules which are transported to the cellular periphery for localized translation. These mechanisms are important for asymmetric mRNA and protein distribution and have profound impact on cellul

- Heterogeneous ribonucleoproteins (hnRNPs) have key roles in RNA biogenesis, including pre-mRNP assembly, transport and cytoplasmic localization. Here we show by biochemical fractionation of nuclear extracts and protein-protein interaction assays that the A/B-type hnRNP CBF-A is in a multiprotein com
