Description
WRN helicase is a multifunctional enzyme that has both magnesium and ATP-dependent DNA-helicase activity and 3'->5' exonuclease activity towards double-stranded DNA with a 5'-overhang. It has no nuclease activity towards single-stranded DNA or blunt-ended double-stranded DNA. It binds preferentially to DNA substrates containing alternate secondary structures, such as replication forks and Holliday junctions. It 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. It alleviates the stalling of DNA polymerases at the site of DNA lesions and is important for genomic integrity. It plays a role in the formation of DNA replication focal centers; stably associates with foci elements generating binding sites for RP-A (By similarity) and plays a role in double-strand break repair after gamma-irradiation.
