Crystal structure of the Bloom's syndrome helicase BLM in complex with DNA

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]

About this Structure

4cgz is a 3 chain structure. Full crystallographic information is available from OCA.
