Summary
Predicted to enable DNA binding activity and nuclease activity. Predicted to be involved in DNA catabolic process, endonucleolytic; DNA catabolic process, exonucleolytic; and DNA repair. Predicted to be located in nuclear speck and nucleolus. Predicted to be active in nucleus. Is expressed in several structures, including alimentary system; brain; cardiovascular system; connective tissue; and genitourinary system. Orthologous to human REXO4 (REX4 homolog, 3'-5' exonuclease). [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.

RNA

  1. NR_156410.1 RNA Sequence

    Status: VALIDATED

    Description
    Transcript Variant: This variant (3) lacks an alternate exon compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
