The tumor suppressor protein BRCA2 promotes efficient repair of damaged chromosomes by homologous recombination, and it does so by influencing the activity of the Rad51 recombinase. A new biochemical study on the Ustilago maydis BRCA2 ortholog Brh2 sheds light on the molecular function of this tumor suppressor in the Rad51-mediated homologous recombination reaction.
