Synthetic Lethality
A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Histone H3 K56 hyperacetylation perturbs replisomes and causes DNA damage.
Deacetylation of histone H3 K56, regulated by the sirtuins Hst3p and Hst4p, is critical for maintenance of genomic stability. However, the physiological consequences of a lack of H3 K56 deacetylation are poorly understood. Here we show that cells lacking Hst3p and Hst4p, in which H3 K56 is constitutively hyperacetylated, exhibit hallmarks of spontaneous DNA damage, such as activation of the ... [more]
