ターゲット情報

  • 機能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.
  • 関連疾患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].
  • 配列類似性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.
  • 翻訳後修飾Phosphorylated by PRKDC. Phosphorylated upon DNA damage, probably by ATM or ATR.

  • Predicted band size : 160 kDa

    Lane 1: Wild-type HAP1 cell lysate (20 µg)
    Lane 2: Werner's syndrome helicase WRN knockout HAP1 cell lysate (20 µg)
    Lane 3: MOLT4 cell lysate (20 µg)
    Lane 4: K562 cell lysate (20 µg)
    Lanes 1 to 4: Merged signal (red and green). Green - ab66601 observed at 170 kDa. Red - loading control, ab181602, observed at 37 kDa.
    ab66601 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. ab66601 and ab181602 (loading control to GAPDH) were both diluted at 1/500 and 1/10 000 and incubated overnight at 4°C. Blots were developed with goat anti-rabbit IgG (H + L) and goat anti-mouse IgG (H + L) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.

    Western blot analysis by ab66601 of WRN helicase protein in the EBV-transformed cells from WS (Werner syndrome) patient cells and normal individuals.
  • ICC/IF image of ab66601 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab66601, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
