Protein

Bloom syndrome protein homolog

Gene

Blm

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

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 Publication

Catalytic activityi

ATP + H2O = ADP + phosphate.

Interactioni

Subunit structurei

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 ubiquitinated FANCD2. Interacts with RMI complex. Interacts directly with RMI1 (via N-terminal region) component of RMI complex. Interacts with SUPV3L1. Found in a complex, at least composed of BLM, RAD51 and SPIDR; the complex formation is mediated by SPIDR. 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 By similarity.By similarity
