Summary: Enables 3'-5' exonuclease activity. Involved in DNA replication and G-quadruplex DNA unwinding. Acts upstream of or within several processes, including determination of adult lifespan; regulation of growth rate; and replicative senescence. Located in chromosome, telomeric region; nucleoplasm; and replication fork. Is expressed in coelomic epithelium of testis; metanephros; and spleen. Used to study Werner syndrome. Human ortholog(s) of this gene implicated in Werner syndrome; breast cancer; coronary artery disease (multiple); diffuse scleroderma; and senile cataract. Orthologous to human WRN (WRN RecQ like helicase). [provided by Alliance of Genome Resources, Dec 2024]

WRN helicase safeguards deprotected replication forks in BRCA2-mutated cancer cells.
Title: WRN helicase safeguards deprotected replication forks in BRCA2-mutated cancer cells.
These results suggest that a great number of endoplasmic reticulum (ER) gene products are regulated at the post-transcriptional level in the liver of Wrn mutant mice exhibiting an ER stress response.
Title: Vitamin C alters the amount of specific endoplasmic reticulum associated proteins involved in lipid metabolism in the liver of mice synthesizing a nonfunctional Werner syndrome (Wrn) mutant protein.
A mislocalization of the Wrn mutant protein in the liver endoplasmic reticulum fraction increased oxidative stress in that cellular compartment. Vitamin C reversed this oxidative stress.

Studies show that in the context of Myc-associated tumorigenesis, loss of Wrn amplifies the DNA damage response, both in preneoplastic and neoplastic tissue, engaging activation of tumor suppressor pathways.
Title: MYC-driven tumorigenesis is inhibited by WRN syndrome gene deficiency.
embryonic fibroblasts lacking a functional Wrn helicase inhibited the immortalization of Safb1-null cells. These results indicate that an intact Wrn protein is required for immortalization and tumorigenesis in Safb1-null mice.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
