== Function ==
[https://www.uniprot.org/uniprot/EXRBN_MYCTU EXRBN_MYCTU] Exonuclease that cleaves single-stranded 3' overhangs of double-stranded RNA. Has no activity with 5' overhangs. Has negligible endonuclease activity. Can bind ATP, dATP and AMP (in vitro); the nucleotide occupies the predicted substrate binding site.<ref>PMID:24311791</ref>
