Abstract


Cdc13, Stn1 and Ten1 are essential yeast proteins that both protect chromosome termini from unregulated resection and regulate telomere length. Cdc13, which localizes to telomeres through high-affinity binding to telomeric single-stranded DNA, has been extensively characterized, whereas the contribution(s) of the Cdc13-associated Stn1 and Ten1 proteins to telomere function have remained unclear. We show here that Stn1 and Ten1 are DNA-binding proteins with specificity for telomeric DNA substrates. Furthermore, Stn1 and Ten1 show similarities to Rpa2 and Rpa3, subunits of the heterotrimeric replication protein A (RPA) complex, which is the major single-stranded DNA-binding activity in eukaryotic cells. We propose that Cdc13, Stn1 and Ten1 function as a telomere-specific RPA-like complex. Identification of an RPA-like complex that is targeted to a specific region of the genome suggests that multiple RPA-like complexes have evolved, each making individual contributions to genomic stability.
