Probable component of the exosome 3'->5' exoribonuclease complex, a complex that degrades inherently unstable mRNAs containing AU-rich elements (AREs) within their 3'-untranslated regions. May form a homodimer separately from exosome complexes and function in DNA cleavage process. Binds double-stranded DNA (dsDNA) and single-stranded RNA (ssRNA), and possesses hydrolytic DNase and phosphorolytic RNase activities in vitro.
