RNA processing machineries in Archaea: the 5’-3’ exoribonuclease aRNase J of the β-CASP family is engaged specifically with the helicase ASH-Ski2 and the 3’-5’ exoribonucleolytic RNA exosome machinery

Duy Khanh Phung, Clarisse Etienne, Manon Batista, Petra S. Langendijk-Genevaux, Yann Moalic, Sébastien Laurent, Sophie Liuu, Violette Morales, Mohamed Jebbar, Gwennaele A. Fichant, Marie Bouvier, Didier Flament, Béatrice Clouet-d’Orval

The paper identifies aRNase J, a 5’-3’ exoribonuclease in Archaea, as part of a complex with ASH-Ski2 helicase and the RNA exosome, suggesting its role in RNA surveillance and translation.
