Function

ATP-dependent DNA helicase that unwinds single- and double-stranded DNA in a 3'-5' direction. Participates in DNA replication and repair. 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.

Biological Context

Subcellular Location: Nucleus
Tissue Specificity: Highly expressed in testis 12-14 days after birth (corresponding to the pachytene phase) and at much lower levels in brain, heart, liver, lung, thymus, kidney and spleen. Expressed in bone marrow

Function

ATP-dependent DNA helicase that unwinds single- and double-stranded DNA in a 3'-5' direction (PubMed:9840919). Participates in DNA replication and repair (By similarity). 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:9840919). Negatively regulates sister chromatid exchange (SCE) (PubMed:27010503, PubMed:9840919). Stimulates DNA 4-way junction branch migration and DNA Holliday junction dissolution. Unwinds G-quadruplex DNA. Binds single-stranded DNA (ssDNA), forked duplex DNA and DNA Holliday junction (By similarity). Recruited by the KHDC3-OOEP scaffold to DNA replication forks where it is retained by TRIM25 ubiquitination, it thereby promotes the restart of stalled replication forks

Subunit

Monomer. Homodimer (via N-terminus). Homotetramer (via N-terminus); dimer of dimers. Homohexamer (via N-terminus). Self-association negatively regulates DNA unwinding amplitude and rate. Oligomer complexes dissociate into monomer in presence of ATP. Part of the BRCA1-associated genome surveillance complex (BASC), which contains BRCA1, MSH2, MSH6, MLH1, ATM, BLM, PMS2 and the RAD50-MRE11-NBS1 protein complex. This association could be a dynamic process changing throughout the cell cycle and within subnuclear domains. Interacts with RMI complex. Interacts directly with RMI1 (via N-terminal region) component of RMI complex. Found in a complex, at least composed of BLM, RAD51 and SPIDR; the complex formation is mediated by SPIDR. Interacts with the KHDC3/FILIA-OOEP/FLOPED scaffold complex and TRIM25 at DNA replication forks (PubMed:29125140). Interacts with ubiquitinated FANCD2 (By similarity). Interacts with SUPV3L1 (By similarity). Interacts with TOP3A (via N-terminal region). Interacts with SPIDR (via C-terminal region); the interaction is direct and required to target BLM to sites of DNA damage
