Abstract
RAD52 rejoins resected broken DNA ends by mediating single-strand annealing. Our recent work elucidates that FANCA, a Fanconi anemia protein, also directly repairs double-strand breaks (DSBs) by catalyzing annealing of single-stranded DNA. FANCA and RAD52 likely play complementary roles to each other to prevent deleterious consequences of DSBs.
