Function
Multifunctional enzyme that has magnesium and ATP-dependent 3'-5' DNA-helicase activity on partially duplex substrates (PubMed:9224595, PubMed:9288107, PubMed:9611231). Also has 3'->5' exonuclease activity towards double-stranded (ds)DNA with a 5'-overhang (PubMed:11863428). Has no nuclease activity towards single-stranded (ss)DNA or blunt-ended dsDNA (PubMed:11863428). Helicase activity is most efficient with (d)ATP, but (d)CTP will substitute with reduced efficiency; strand displacement is enhanced by single-strand binding-protein (heterotrimeric replication protein A complex, RPA1, RPA2, RPA3) (PubMed:9611231). 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. Plays a role in the formation of DNA replication focal centers; stably associates with foci elements generating binding sites for RP-A (By similarity). Plays a role in double-strand break repair after gamma-irradiation (PubMed:9224595, PubMed:9288107, PubMed:9611231). Unwinds some G-quadruplex DNA (d(CGG)n tracts); unwinding seems to occur in both 5'-3' and 3'-5' direction and requires a short single-stranded tail (PubMed:10212265). d(CGG)n tracts have a propensity to assemble into tetraplex structures; other G-rich substrates from a telomeric or IgG switch sequence are not unwound (PubMed:10212265). Depletion leads to chromosomal breaks and genome instability (PubMed:33199508).

Supplementary info

- Activity summary
Werner's syndrome helicase also known as WRN plays a mechanical role in DNA replication and repair. WRN is a 160 kDa protein containing both helicase and exonuclease activities making it unique among RecQ helicases. It unwinds DNA duplexes and resolves complex DNA structures that can arise during replication and repair processes. WRN is expressed in the nucleus of various cell types including fibroblasts where it maintains genome stability. This helicase is critical in processing DNA intermediates to prevent genomic instability.
- Biological function summary
WRN functions as a part of larger protein complexes that participate in DNA damage response and repair. It interacts with several proteins involved in the homologous recombination and base excision repair pathways. WRN's unique enzymatic activities enable it to stabilize and process DNA ends during replication fork collapse and double-strand break repair. By operating in concert with proteins such as RAD51 and replication protein A (RPA) WRN ensures accurate replication and repair preventing mutation accumulation.
- Pathways
WRN plays a central role in the maintenance of genomic integrity through its involvement in DNA repair pathways and the aging process. It is integral to the process of homologous recombination where it works closely with the MRE11-RAD50-NBS1 (MRN) complex. Additionally WRN has a function in the DNA damage checkpoint pathway collaborating with proteins like ATM and ATR which help to sense damaged DNA and initiate repair processes. These pathways are important for maintaining DNA integrity and preventing cellular senescence.
- Associated diseases and disorders
WRN is closely linked to Werner syndrome and cancer. Mutations in the WRN gene lead to Werner syndrome a rare disorder characterized by premature aging and cancer predisposition. WRN's interaction with tumor suppressor proteins such as p53 connects it to pathways that can contribute to tumorigenesis when dysregulated. Understanding WRN's function and its role in these diseases provides insight into mechanisms of aging and cancer development offering potential therapeutic targets.
