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.

Proteasomal ATPases link ubiquitylation of histone H2B to methylation of histone H3.
In Saccharomyces cerevisiae, methylation of histone H3 at active genes is an epigenetic mark that distinguishes active from silent chromatin and functions as a short-term "memory" of recent transcription. Methylation of H3 at lysine residues K4 and K79 depends on ubiquitylation of histone H2B, but the mechanisms linking H2B ubiquitylation to H3 methylation are unknown. Here, we demonstrate that proteasomal ... [more]
