In Saccharomyces cerevisiae, a DNA damage checkpoint in the S-phase is responsible for delaying DNA replication in response to genotoxic stress. This pathway is partially regulated by the checkpoint proteins Rad9, Rad17 and Rad24. Here, we describe a novel hypermutable phenotype for rad9Delta, rad17Delta and rad24Delta cells in response to a chronic 0.01% dose of the DNA alkylating agent MMS. We report that this hypermutability results from DNA damage introduction during the S-phase and is depen ...[more]
