    Summary
    Enables DNA binding activity; metal ion binding activity; and nuclease activity. Acts upstream of or within DNA repair and DNA replication. Predicted to be located in mitochondrion; nucleolus; and nucleoplasm. Predicted to be part of protein-containing complex. Predicted to be active in nucleus. Predicted to colocalize with chromosome, telomeric region. Is expressed in several structures, including brain; genitourinary system; liver; lung; and spleen. Orthologous to human FEN1 (flap structure-specific endonuclease 1). [provided by Alliance of Genome Resources, Dec 2024]

    1. Kinetic measurements showed that the active site mutants A159V and E160D reduce the rates of hydrolysis under multiple- and single-turnover conditions on all substrates. Consistent with their dominant negative effects in heterozygotes, neither mutation affects the adoption of the substrate duplex arms in the bent conformation on the enzyme surface, although decreases in substrate binding affinity are observed.

    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.
