  • FunctionMultifunctional 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 diseaseDefects 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 similaritiesBelongs 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.

Thank you for your enquiry. You ask an interesting question. I have been in discussion with the lab and they have referred me to the fact that the resolution of proteins by SDS-PAGE does not define molecular weight. It defines the relative mobilit...
