ABSTRACT
Defective RNAs and proteins are swiftly degraded by cellular quality control mechanisms. A large fraction of their degradation is mediated by the exosome and the proteasome. These complexes have a similar architectural framework based on cylindrical, hollow structures that are conserved from bacteria and archaea to eukaryotes. Mechanistic similarities have also been identified for how RNAs and proteins are channelled into these structures and prepared for degradation. Insights gained from studies of the proteasome should now set the stage for elucidating the regulation, assembly and small-molecule inhibition of the exosome.
