    Summary
    Enables several functions, including 5'-3' exonuclease activity; hydrolase activity, acting on acid anhydrides, in phosphorus-containing anhydrides; and magnesium ion binding activity. Involved in NAD-cap decapping; RNA destabilization; and nuclear mRNA surveillance. Predicted to be located in nucleoplasm and plasma membrane. Predicted to be active in cytosol and nucleus. Orthologous to human DXO (decapping exoribonuclease). [provided by Alliance of Genome Resources, Dec 2024]

    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.
