Disease

BLM_HUMAN Bloom syndrome. The disease is caused by mutations affecting the gene represented in this entry.

Function

BLM_HUMAN Participates in DNA replication and repair. Exhibits a magnesium-dependent ATP-dependent DNA-helicase activity that unwinds single- and double-stranded DNA in a 3'-5' direction. 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. Negatively regulates sister chromatid exchange (SCE).^[1] ^[2] ^[3] ^[4]
