  • Target

    • Function

      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.
    • Involvement in disease

      Defects in WRN are a cause of Werner syndrome (WRN) [MIM:277700]. WRN is a rare autosomal recessive progeroid syndrome characterized by the premature onset of multiple age-related disorders, including atherosclerosis, cancer, non-insulin-dependent diabetes mellitus, ocular cataracts and osteoporosis. The major cause of death, at a median age of 47, is myocardial infarction. Currently all known WS mutations produces prematurely terminated proteins.
      Defects in WRN may be a cause of colorectal cancer (CRC) [MIM:114500].
    • Sequence similarities

      Belongs to the helicase family. RecQ subfamily.
      Contains 1 3'-5' exonuclease domain.
      Contains 1 helicase ATP-binding domain.
      Contains 1 helicase C-terminal domain.
      Contains 1 HRDC domain.
    • Post-translational

      Phosphorylated by PRKDC. Phosphorylated upon DNA damage, probably by ATM or ATR.

      ab124673 was shown to recognize Werner's syndrome helicase WRN when Werner's syndrome helicase WRN knockout samples were used, along with additional cross-reactive bands. Wild-type and Werner's syndrome helicase WRN knockout samples were subjected to SDS-PAGE. ab124673 and ab181602 (loading control to GAPDH) were both diluted at 1/1000 and 1/10000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preadsorbed ab216772 and Goat Anti-Rabbit IgG H&L (IRDye® 680RD) preadsorbed ab216777 secondary antibodies at 1/10000 dilution for 1 h at room temperature before imaging.
