BAIT

VMS1

YDR049W
Component of a Cdc48p-complex involved in protein quality control; exhibits cytosolic and ER-membrane localization, with Cdc48p, during normal growth, and contributes to ER-associated degradation (ERAD) of specific substrates at a step after their ubiquitination; forms a mitochondrially-associated complex with Cdc48p and Npl4p under oxidative stress that is required for ubiquitin-mediated mitochondria-associated protein degradation (MAD); conserved in C. elegans and humans

YBL057C
One of two mitochondrially-localized peptidyl-tRNA hydrolases; negatively regulates the ubiquitin-proteasome pathway via interactions with ubiquitin-like ubiquitin-associated proteins; dispensable for cell growth; see also PTH1

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.

Ribosome-associated protein quality control (RQC) protects cells against the toxic effects of faulty polypeptides produced by stalled ribosomes. However, mitochondria are vulnerable to C-terminal alanyl and threonyl (CAT)-tailed proteins that are generated in this process, and faulty nuclear-encoded mitochondrial proteins are handled by the recently discovered mitoRQC. Here, we performed a genome-wide screen in yeast to identify additional proteins involved ... [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.
