Rap1 is a telomeric protein that is highly expressed in cancers. Here, the authors show that Rap1 interacts with several DNA repair proteins independent of its telomere function to enhance DNA repair and that its deficiency leads to accelerated tumorigenesis, but enhanced sensitivity to genotoxic stress.
