From Wikipedia, the free encyclopedia. Werner syndrome ATP-dependent helicase also known as DNA helicase, RecQ-like type 3 is an enzyme that in humans is encoded by the WRN gene. WRN is a member of the RecQ Helicase family. Helicase enzymes generally unwind and separate double-stranded DNA. These activities are necessary before DNA can be copied in preparation for cell division (DNA replication).
