Function

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). Recruited by the KHDC3L-OOEP scaffold to DNA replication forks where it is retained by TRIM25 ubiquitination, it thereby promotes the restart of stalled replication forks (By similarity).

Activity summary

Blooms Syndrome Protein often abbreviated as BLM functions as a DNA helicase with a mass of approximately 141 kDa. BLM unwinds the DNA duplex important for genomic stability during replication and repair processes. This protein sometimes referred to as Bloom's Protein is expressed in various human tissues with higher levels in proliferating cells. BLM participates actively in the maintenance of genome integrity by resolving recombination intermediates and preventing crossover events.

Biological function summary

The BLM helicase acts as a critical player in the maintenance of chromosomal stability. It forms part of a complex known as the BLM complex which includes topoisomerase IIIα RMI1 and RMI2. This complex participates in homologous recombination repair ensuring proper disjunction of intertwined DNA and preventing excessive sister chromatid exchanges. This function is essential for preventing genomic instability which may lead to cell dysfunction or malignancies.

Pathways

The BLM protein associates with the DNA damage response and homologous recombination repair pathways. BLM interacts directly with components of the BRCA1-associated genome surveillance complex and indirectly with the ATM-dependent DNA damage signaling pathways to coordinate DNA repair processes. Its cooperation with proteins like RAD51 is integral for efficient DNA repair and recovery during replication stress conditions.

Associated diseases and disorders

Bloom Syndrome directly relates to mutations or dysfunction in BLM. This rare genetic disorder leads to increased susceptibility to various cancers due to high rates of genomic instability and sister chromatid exchanges. In addition anomalies in BLM function may connect it to Werner syndrome where increased genomic instability is observed. Both conditions highlight BLM's role in safeguarding genome integrity and its critical interactions with proteins such as WRN helicase affecting cellular aging and carcinogenesis pathways.
