Cooperation of breast cancer proteins PALB2 and piccolo BRCA2 in stimulating homologous recombination

Tumor suppressor PALB2 is known to interact with BRCA2 and promote homologous recombination in vivo. Now PALB2's activities have been studied, together with a BRCA2 chimeric protein, revealing that PALB2 binds D-loop structures, interacts directly with RAD51 and promotes strand invasion synergistically with BRCA2.
