WebThe yeast RNA exosome consists of a highly conserved 9-subunit core complex and two catalytic subunits, Rrp44 and Rrp6. Rrp44 is bound with exosome core both in cytoplasm and nucleus, while Rrp6 is unique in nucleus. The yeast cytoplasmic exosome has a Ski7 protein that bridges the complex to Ski complex for degradation of aberrant mRNAs. WebJan 11, 2006 · Exosome Subunits in Distinct Cytoplasmic Compartments.
