[The WS gene encodes WRN, a 1,432-amino acid polypeptide. WRN is a member of the RecQ family of DNA helicases that unwind duplex DNA. It can also digest DNA exonucleolytically with 3'-5' polarity. WRN may facilitate pol d-mediated DNA replication and/or DNA repair and disruption of WRN-DNA polymerase delta interaction in WS cells may contribute to the S-phase defects and/or the unusual sensitivity to a limited number of DNA damaging agents.
