Abstract


3' to 5' RNA degradation is primarily catalyzed by the RNA exosome subunits Dis3 and Rrp6 in the nucleus of Saccharomyces cerevisiae. These enzymes form a complex with the nine-subunit noncatalytic core (Exo9) to carry out their functions in vivo. Protein cofactors Rrp47, Mpp6, and the Mtr4 RNA helicase also assist the complex by modulating its activities and/or recruiting it to specific RNAs for processing or degradation. Here we present our preferred strategy for reconstituting RNA exosomes from S. cerevisiae using purified, recombinantly expressed components.
