Protein: RecQ-like DNA helicase blm-1 (EC 5.6.2.4) (Bloom syndrome protein homolog) (DNA 3'-5' helicase BLM) (High incidence of males protein 6) (RecQ helicase homolog) (O18017)
Organism: Caenorhabditis elegans
Function: Component of the BTR double Holliday Junction dissolution complex, which is involved in homologous recombination during meiotic double strand break in the germline (Probable). Stabilizes and positively regulates the localization of the BTR double Holliday Junction dissolution complex component rmh-1 at nuclear foci during meiotic recombination. Participates in DNA replication and repair (By similarity). Exhibits a magnesium-dependent ATP-dependent DNA-helicase activity that unwinds single- and double-stranded DNA in a 3'-5' direction (By similarity). Negatively regulates sister chromatid exchange (SCE).
Subcellular location: Nucleus {ECO:0000269|PubMed:27011106, ECO:0000269|PubMed:34252074}. Chromosome {ECO:0000269|PubMed:27011106}. Note=Localizes on chromosomes during pachytene in meiotic prophase I in oocytes. Co-localizes with rmh-1 at mid-pachytene and late-pachytene in meiotic prophase I (PubMed:27011106). Localization at nuclear foci is dependent on rmh-1 during meiotic recombination (PubMed:27011106). {ECO:0000269|PubMed:27011106, ECO:0000269|PubMed:34252074}.
