In homologous recombination (HR), a crucial eukaryotic DNA recombinase called RAD51 encourages homologous pairing and strand exchange in addition to the recombinational repair of double strand breaks. The homopolymeric filaments created by RAD51 protein, which is attracted to the DNA break by BRCA2, invade the homologous chromatid and use it as a template for repair. The presence of RAD51 filaments, which can be seen by immunofluorescence as distinct foci in the cell nucleus, serves as a readout of HR competence. RAD51 is a crucial gene that guards against genetic instability in cells.

The activity of the RAD51 recombinase is essential for the survival and proliferation of cancer cells, and it frequently results in drug resistance. Breast cancer and chronic myeloid leukemia (CML) have been found to have abnormally elevated RAD51 function and hyperactive homologous recombination (HR) rates. Therefore, RAD51 direct targeting and RAD51 activity attenuation have been suggested as an additional and alternative cancer treatment method.
