Protein Structure
UniProt Annotation
Function Interferon-induced antiviral exoribonuclease that acts on single-stranded RNA and also has minor activity towards single- stranded DNA. Exhibits antiviral activity against RNA viruses in an exonuclease-dependent manner. May also play additional roles in the maturation of snRNAs and rRNAs, and in ribosome biogenesis (By similarity). {ECO:0000250}.
Subcellular Localization Nucleus {ECO:0000250}. Nucleus, nucleolus {ECO:0000250}. Cytoplasm {ECO:0000250}. Nucleus, Cajal body {ECO:0000250}.
