Summary
Predicted to enable 3'-5' exonuclease activity and RNA binding activity. Predicted to be involved in defense response to virus; negative regulation of viral genome replication; and nucleobase-containing compound catabolic process. Predicted to act upstream of or within innate immune response and rRNA processing. Predicted to be located in cytoplasm and nuclear lumen. Predicted to be active in nucleus. Is expressed in liver lobe. Orthologous to human ISG20 (interferon stimulated exonuclease gene 20). [provided by Alliance of Genome Resources, Apr 2022]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

    Description
    Transcript Variant: This variant (2) differs in the 5' UTR and uses an alternate splice junction at the 5' end of the last exon compared to variant 4. The resulting isoform (b) has a shorter and distinct C-terminus compared to isoform a. Variants 1, 2, and 3 all encode the same isoform (b).
