WRN (Werner Syndrome RecQ Like Helicase) is a RecQ family DNA helicase/exonuclease that plays essential roles in DNA replication, repair, and recombination. WRN is unique among RecQ helicases in possessing both 3'→5' helicase and 3'→5' exonuclease activities. Biallelic mutations in WRN cause Werner syndrome, a rare autosomal recessive disorder characterized by premature aging (progeria), beginning in adolescence/early adulthood. The WRN protein is critically involved in maintaining genomic integrity in neurons and other cell types, and its dysfunction contributes to age-related neurodegeneration.
WRN is a multifunctional DNA metabolic enzyme:
