Abstract

Common fragile sites (CFSs) tend to break upon replication stress and have been suggested to be "hot spots" for genomic instability. Recent evidence, however, implies that in the wake of DNA damage, WW domain-containing oxidoreductase (WWOX, the gene product of the FRA16D fragile site), associates with ataxia telangiectasia-mutated (ATM) and regulates its activation to maintain genomic integrity.
