Previous GeneCards Identifiers for BLM Gene
The Bloom syndrome gene product is related to the RecQ subset of DExH box-containing DNA helicases and has both DNA-stimulated ATPase and ATP-dependent DNA helicase activities. Mutations causing Bloom syndrome delete or alter helicase motifs and may disable the 3'-5' helicase activity. The normal protein may act to suppress inappropriate recombination.

BLM (Bloom Syndrome RecQ Like Helicase) is a Protein Coding gene. Diseases associated with BLM include Bloom Syndrome and Werner Syndrome. Among its related pathways are SUMOylation and Metabolism of proteins. Gene Ontology (GO) annotations related to this gene include nucleic acid binding and ATPase activity. An important paralog of this gene is WRN.
UniProtKB/Swiss-Prot for BLM Gene
ATP-dependent DNA helicase that unwinds single- and double-stranded DNA in a 3-5 direction (PubMed:9388193, PubMed:24816114, PubMed:25901030). Participates in DNA replication and repair (PubMed:12019152, PubMed:21325134, PubMed:23509288). Involved in 5-end resection of DNA during double-strand break (DSB) repair: unwinds DNA and recruits DNA2 which mediates the cleavage of 5-ssDNA (PubMed:21325134). Negatively regulates sister chromatid exchange (SCE) (PubMed:25901030). Stimulates DNA 4-way junction branch migration and DNA Holliday junction dissolution (PubMed:25901030). Binds single-stranded DNA (ssDNA), forked duplex DNA and DNA Holliday junction (PubMed:20639533, PubMed:24257077, PubMed:25901030).
