    Summary
    Enables 3'-5' DNA helicase activity. Involved in G-quadruplex DNA unwinding; negative regulation of mitotic recombination; and replication fork processing. Acts upstream of or within several processes, including DNA metabolic process; T cell differentiation; and positive regulation of T cell proliferation. Located in chromosome; cytoplasm; and nucleus. Is expressed in several structures, including brain; genitourinary system; gut; hemolymphoid system gland; and mammary gland. Used to study Bloom syndrome. Human ortholog(s) of this gene implicated in Bloom syndrome. Orthologous to human BLM (BLM RecQ like helicase). [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.
