Abstract:
| We define a DNA damage checkpoint pathway in S. cerevisiae governed by the ATM homolog Tel1 and the Mre11 complex. In mitotic cells, the Tel1-Mre11 complex pathway triggers Rad53 activation and its interaction with Rad9, whereas in meiosis it acts via Rad9 and the Rad53 paralog Mre4/Mek1. Activation of the Tel1-Mre11 complex pathway checkpoint functions appears to depend upon the Mre11 complex as a damage sensor and, at least in meiotic cells, to depend on unprocessed DNA double-strand breaks (DSBs). The DSB repair functions of the Mre11 complex are enhanced by the pathway, suggesting that the complex both initiates and is regulated by the Tel1-dependent DSB signal. These findings demonstrate that the diverse functions of the Mre11 complex in the cellular DNA damage response are conserved in mammals and yeast. |
