    Summary
    Predicted to enable single-stranded 3'-5' DNA helicase activity. Involved in positive regulation of double-strand break repair via homologous recombination. Predicted to be part of single-stranded DNA-dependent ATP-dependent DNA helicase complex. Predicted to be active in nucleus and site of DNA damage. Orthologous to human HELQ (helicase, POLQ like). [provided by Alliance of Genome Resources, Nov 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.
