General Information
Term nuclear exosome (RNase complex) ID (Ontology) GO:0000176 (Gene Ontology)
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.[ PubMed:17174896 PubMed:20531386 PubMed:26726035 ]
Also Known As "eukaryotic exosome multienzyme ribonuclease complex" ; "nuclear exosome (ribonuclease complex)" ; "nuclear exosome multienzyme ribonuclease complex"
