Term Name:	nuclear exosome (RNase complex)
Synonyms:	eukaryotic exosome multienzyme ribonuclease complex, nuclear exosome (ribonuclease complex), nuclear exosome multienzyme ribonuclease complex
Definition:	A ribonuclease complex that has 3-prime to 5-prime processive and distributive hydrolytic exoribonuclease activity and endoribonuclease activity, producing 5-prime-phosphomonoesters. Participates in a multitude of cellular RNA processing and degradation events preventing nuclear export and/or translation of aberrant RNAs. Restricted to processing linear and circular single-stranded RNAs (ssRNA) only. RNAs with complex secondary structures may have to be unwound or pre-processed by co-factors prior to entering the complex, esp if the 3-prime end is structured.
