Human FANCD2 and BLM act in one pathway to mediate replication fork restart and suppression of new origin firing. (A) Human cell types used for DNA fiber analysis : wild type (PD20 + D2, siControl), FANCD2 deficient (PD20, siControl), BLM deficient (PD20 + D2, siBLM) and FANCD2/BLM double deficient (PD20, siBLM). (B) Images of DNA fibers with a schematic of defining sites of replication. Red tracts : DigU; green tracts : BioU. (C) FANCD2 and BLM act in a common pathway to mediate replication fork restart after replication blockade. The efficiency of replication restart in wild-type, FANCD2-deficient, BLM-deficient and FANCD2/BLM double-deficient cells was measured as the number of restarted replication forks after APH-mediated fork stalling (DigU→BioU tracts), compared with the total number of DigU-labeled tracts (DigU plus DigU→BioU). (D) FANCD2 and BLM act in concert to suppress new origin firing during replication blockade. The number of new sites of replication originating during the 40 min recovery period after APH treatment was compared between wild-type, FANCD2-deficient, BLM-deficient and FANCD2/BLM double-deficient cells. New origins of replication were measured as the number of green-only (BioU) tracts per unit length. ***p < 0.0001.

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.

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.

靶点信息

ATP-dependent DNA helicase that unwinds double-stranded (ds)DNA in a 3'-5' direction (PubMed : 24816114, PubMed : 25901030, PubMed : 9388193, PubMed : 9765292). Participates in DNA replication and repair (PubMed : 12019152, PubMed : 21325134, PubMed : 23509288, PubMed : 34606619). 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). Stimulates DNA 4-way junction branch migration and DNA Holliday junction dissolution (PubMed : 25901030). Binds single-stranded DNA (ssDNA), forked duplex DNA and Holliday junction DNA (PubMed : 20639533, PubMed : 24257077, PubMed : 25901030). Unwinds G-quadruplex DNA; unwinding occurs in the 3'-5' direction and requires a 3' single-stranded end of at least 7 nucleotides (PubMed : 18426915, PubMed : 9765292). Helicase activity is higher on G-quadruplex substrates than on duplex DNA substrates (PubMed : 9765292). Telomeres, immunoglobulin heavy chain switch regions and rDNA are notably G-rich; formation of G-quadruplex DNA would block DNA replication and transcription (PubMed : 18426915, PubMed : 9765292). Negatively regulates sister chromatid exchange (SCE) (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).. (Microbial infection) Eliminates nuclear HIV-1 cDNA, thereby suppressing immune sensing and proviral hyper-integration.
