Target Background

Multifunctional enzyme that has both magnesium and ATP-dependent DNA-helicase activity and 3'->5' exonuclease activity towards double-stranded DNA with a 5'-overhang. Has no nuclease activity towards single-stranded DNA or blunt-ended double-stranded DNA. Binds preferentially to DNA substrates containing alternate secondary structures, such as replication forks and Holliday junctions. May play an important role in the dissociation of joint DNA molecules that can arise as products of homologous recombination, at stalled replication forks or during DNA repair. Alleviates stalling of DNA polymerases at the site of DNA lesions. Important for genomic integrity. Plays a role in the formation of DNA replication focal centers; stably associates with foci elements generating binding sites for RP-A. Plays a role in double-strand break repair after gamma-irradiation.

  5. In the Title. PMID: 28012115
  6. Data show that helicases RHAU, BLM, and WRN exhibit distinct G-quadruplex (GQ) conformation specificity, but use a common mechanism of repetitive unfolding that leads to disrupting GQ structure multiple times in succession. PMID: 27407146
  7. there was no consistent association between WRN promoter hypermethylation and loss of WRN expression at the mRNA or protein level in CRC cell lines or tumors. PMID: 27121793

  9. WRN is essential for survival of ATLL cells PMID: 27829440
  10. The authors show that the helicase of hDNA2 functionally integrates with BLM or WRN helicases to promote double-stranded DNA degradation by forming a heterodimeric molecular machine. This collectively suggests that the human DNA2 motor promotes the enzyme's capacity to degrade double-stranded DNA in conjunction with BLM or WRN and thus promote the repair of broken DNA. PMID: 27612385
  11. In meta-analyses including 59,190 individuals in 5 studies, the hazard ratio for ischemic stroke for C1367R TT homozygotes versus CC/CT was 1.14 . The study suggests that common genetic variation in WRN is associated with increased risk of ischemic stroke in the general population. PMID: 28063943
  12. The findings suggest that the epidermis is among the tissue types that do not display symptoms of premature ageing caused by loss of function of wrn. This is in support that Werner's syndrome is a segmental progeroid syndrome. PMID: 27492502

  18. Our results identify the human WRN RECQ protein as a G4 helicase that modulates gene expression in G4-dependent fashion at many chromosomal sites and provide several new and unexpected mechanistic insights into Werner syndrome (WS) disease pathogenesis PMID: 26984941
  19. WRN or the Bloom syndrome helicase (BLM) stimulates DNA polymerase delta progression across telomeric G-rich repeats, only WRN promotes sequential strand displacement synthesis and FEN1 cleavage. PMID: 27849570
  20. This study identified residues in the WRN RQC domain that are involved specifically in the interaction with G-quadruplex DNA. PMID: 28069813
