| colocalizing with RPA heterotrimeric ss DNA binding protein in meiotic prophase nuclei of spermatocytes division, cell cycle, M, prophase |
|
colocalizing transitorily with RPA, PML in nuclear bodies |
|
present in replication fork |
|
in mitotic cells, BLM and RMI2 were mostly present in the nucleoplasm |
|
BLM is expressed only in dividing cells; it is absent or greatly reduced in quiescent stem cells or in terminally differentiated non-dividing cell |
basic FUNCTION
| DNA helicase, ATP-dependent, atypical and highly DNA structure specific, unwinding single and double strand DNA in a 3'->5' direction, promoting an ATP-dependent branch migration of Holliday junctions |
|
putatively suppressor of homologous recombination between closely opposed and replicating strands, and selected target during the execution of apoptosis |
|
playing a role in recombination-mediated telomere lengthening |
|
DNA damage sensor signaling the formation of DNA damage induced foci |
|
playing a conserved role in recovery from perturbations in DNA replication and likely RecQ helicases act to restore productive DNA replication following S-phase arrest and hence prevent subsequent genomic instability |
|
playing a role in chromosome segregation in addition to its function during DNA replication and repair |
|
involved in the promotion of single-stranded DNA (ssDNA) annealing |
|
functioning in dissociating alternative DNA structures during recombination and/or replication at telomeric ends |
|
with TOP3A execute the dissolution of sister chromatids |
|
might be involved in both early and late steps of homologous recombination |
|
might regress replication forks as part of a genome maintenance pathway |
|
having an anti-recombination role |
|
involved in disruption of the Rad51-ssDNA (single-stranded DNA) filament, an active species that promotes homologous recombination, and stimulation of DNA repair synthesis |
|
playing a a role with EXO1 in the initiation of recombinational DNA repair |
|
stimulating DNA strand exchange activity of RAD51 without ATP hydrolysis |
|
functions as a Holliday junction dissolvase |
|
role in the maintenance of gene cluster genomic integrity |
|
performs double-stranded DNA unwinding by fully active duplex destabilization |
|
regulates several steps of homologous recombination (HR)-dependent repair of double-strand DNA breaks |
|
appears to be a master regulator that is needed by INSL6 as well as by the TOP3/RMI complex to execute diverse functions in order to maintain normal replication and genome stability |
|
BRIP1 catalytic activity and its effect on BLM protein stability contribute to preservation of genomic stability and a normal response to replication stress |
|
WRN and BLM are critical for maintaining genomic stability and thought to function in accurate resolution of replication blockage |
|
ERCC6L and BLM decorate ultrafine histone-negative DNA threads that link the segregating sister centromeres during anaphase |
|
ERCC6L and BLM limit histone association with anaphase centromeric DNA threads and promote their resolution |
|
BLM and RECQL4 have coordinated activities that promote genome stability |
|
ERCC6L and BLM were required for the correct recruitment to the centromere of active TOP2A, an enzyme specialized in the catenation/decatenation process |
|
BLM and ERCC6L cooperate in rendering centromeric catenates accessible to TOP2A, thereby facilitating correct centromere disjunction and preventing the formation of supernumerary centromeric ultrafine anaphase bridges |
|
maintains genome integrity, at least in part, by suppressing illegitimate recombination events |
|
mediates a checkpoint response to stabilize the replication machinery at stalled forks, thereby preventing replisome dissociation and an irreversible fork collapse |
|
possible roles of BLM helicase in the recombination-mediated mechanism of telomere elongation |
|
BLM promotes DNA end resection as part of the BLM-TOP3A-RMI1-RMI2 complex |
|
BLM functions in 2 distinct pathways requiring different modifications: BLM functions to suppress SCE formation and in a second pathway, its phosphorylations are essential for suppression of chromosomal radial formation |
|
BLM helicase has pivotal functions at the crossroads of DNA replication, recombination, and repair |
|
FANCM and BLM complex work together at stalled forks to promote both Fanconi anemia repair and replication traverse pathways of interstrand crosslinks (ICLs) |
