WebJun 23, 2009 · As expected repair had occurred in BRCA2 complemented cells, but in the BRCA2-deficient cells breaks were still present (Figure 3 B), confirming that HR is responsible for a portion of DSB repair following As[III]-induced damage. The persistence of DSBs can lead to apoptosis; therefore we compared apoptosis in V-C8 and V-C8 B2 cells. WebThe BRCA2 protein contains several copies of a 70 aa motif called the BRC motif, and these motifs mediate binding to the RAD51 recombinase which functions in DNA repair. …
