Genomic instability is one of the major components represented in the “Hallmarks of Cancer.” DNA interstrand crosslinks and double-stranded breaks are two of the most severe causes of genomic instability. Homologous recombination (HR) plays a major role in resolving both types of DNA lesions, requiring a homologous template and the RAD51 paralog complex of proteins. One member of this complex is the RAD51D ovarian cancer susceptibility gene product. To better elucidate RAD51D modifications and functions, several protein interaction screens were performed, and one of the novel proteins identified was NONO (a.k.a. p54nrb). Decreased expression of either RAD51D or NONO conferred …
