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.

beta-Subunit appendages promote 20S proteasome assembly by overcoming an Ump1-dependent checkpoint.

Li X, Kusmierczyk AR, Wong P, Emili A, Hochstrasser M

Proteasomes are responsible for most intracellular protein degradation in eukaryotes. The 20S proteasome comprises a dyad-symmetric stack of four heptameric rings made from 14 distinct subunits. How it assembles is not understood. Most subunits in the central pair of beta-subunit rings are synthesized in precursor form. Normally, the beta5 (Doa3) propeptide is essential for yeast proteasome biogenesis, but overproduction of ... [more]

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
