Abstract: The nonhomologous end-joining (NHEJ) repair pathway is inhibited at telomeres, preventing chromosome fusion. In budding yeast Saccharomyces cerevisiae, the Rap1 protein directly binds the telomere sequences and is required for NHEJ inhibition. Here we show that the Rap1 C-terminal domain establishes two parallel inhibitory pathways through the proteins Rif2 and Sir4. In addition, the central domain of Rap1 inhibits NHEJ independently of Rif2 and Sir4. Thus, Rap1 establishes several independent pathways to prevent telomere fusions. We discuss a possible mechanism that would explain Rif2 multifunctionality at telomeres and the recent evolutionary origin of Rif2 from an origin recognition complex (ORC) subunit.
