General description

Anti-WRN antibody, Mouse monoclonal, (mouse IgG1 isotype) is derived from the hybridoma 195C produced by the fusion of mouse myeloma cells (p3-NS1/Ag4-1) and splenocytes from BALB/c mice immunized with a recombinant fusion protein fragment of human WRN. Werner syndrome ATP-dependent helicase (WRN) is located on chromosome 8 and is 167 kDa. The WRN protein belongs to the RecQ helicase family of DNA helicases.

Immunogen

recombinant fusion protein fragment of human WRN (amino acids 1074-1432).

Application

Anti-WRN antibody has been used in
  • enzyme linked immunosorbent assay (ELISA)
  • immunoblotting
  • immunoprecipitation
  • immunohistochemistry
  • western blotting

Biochem/physiol Actions

Werner syndrome ATP-dependent helicase (WRN) protein has been demonstrated to possess three known catalytic activities: 3′-5′ helicase, exonuclease and ATPase activities. The C-terminal region of the protein contains a nuclear localization signal (NLS), thus targeting WRN protein to the nucleus, nucleolus and nucleoplasmic foci. The involvement of WRN in multiple DNA metabolic process suggests its function as a tumor suppressor. Mutations in the WRN protein results in Werner syndrome (WS). The epigenetic inactivation of WRN leads to loss of WRN-exonuclease activity, resulting in increased chromosomal instability and hypersensitivity to chemotherapeutic drugs.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
