Synthetic Rescue
A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.
Publication
Dynamic regulation of single-stranded telomeres in Saccharomyces cerevisiae.
The temperature-sensitive phenotypes of yku70Delta and yku80Delta have provided a useful tool for understanding telomere homeostasis. Mutating the helicase domain of the telomerase inhibitor Pif1 resulted in the inactivation of cell cycle checkpoints and the subsequent rescue of temperature sensitivity of the yku70Delta strain. The inactivation of Pif1 in yku70Delta increased overall telomere length. However, the long G-rich, single-stranded overhangs ... [more]
