Mouse and human cells mutant for BRCA1 or BRCA2 are sensitive to DNA-damaging agents, implicating these genes in the response to DNA damage. Mammalian cells have two major pathways for the repair of DNA double-strand breaks (DSBs), homologous recombination and non-homologous end joining (NHEJ). The BRCA1 and BRCA2 proteins colocalise with RAD51, the mammalian equivalent of the yeast Rad51 protein, which is involved in the repair of DNA DSBs by homologous recombination. This has led to the view that BRCA1 and BRCA2 might also be involved in the repair of DNA DSBs by homologous recombination. …
