Takata H, et al. (2005) Late S phase-specific recruitment of Mre11 complex triggers hierarchical assembly of telomere replication proteins in Saccharomyces cerevisiae. Mol Cell 17(4):573-83
Abstract: In Saccharomyces cerevisiae, telomere replication occurs in late S phase and is accompanied by dynamic remodeling of its protein components. Here, we show that MRX (Mre11-Rad50-Xrs2), an evolutionarily conserved protein complex involved in DNA double-strand break (DSB) repair, is recruited to the telomeres in late S phase. MRX is required for the late S phase-specific recruitment of ATR-like kinase Mec1 to the telomeres. Mec1, in turn, contributes to the assembly of the telomerase regulators Cdc13 and Est1 at the telomere ends. Our results provide a model for the hierarchical assembly of telomere-replication proteins in late S phase; this involves triggering by the loading of MRX onto the chromosome termini. The recruitment of DNA repair-related proteins to the telomeres at particular times in the cell cycle suggests that the normal terminus of a chromosome is recognized as a DSB during the course of replication.
