PDI1
MFP1, TRG1, protein disulfide isomerase PDI1, L000001360, YCL043C
Protein disulfide isomerase; multifunctional protein of ER lumen, essential for formation of disulfide bonds in secretory and cell-surface proteins, unscrambles non-native disulfide bonds; key regulator of Ero1p; forms complex with Mnl1p that has exomannosidase activity, processing unfolded protein-bound Man8GlcNAc2 oligosaccharides to Man7GlcNAc2, promoting degradation in unfolded protein response; PDI1 has a paralog, EUG1, that arose from the whole genome duplication

RIM1, alkaline-responsive transcritional regulator RIM101, L000002818, YHL027W
Cys2His2 zinc-finger transcriptional repressor; involved in alkaline responsive gene repression as part of adaptation to alkaline conditions; involved in cell wall assembly; required for alkaline pH-stimulated haploid invasive growth and sporulation; activated by alkaline-dependent proteolytic processing which results in removal of the C-terminal tail; similar to A. nidulans PacC

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.
Publication
The unfolded protein response is necessary but not sufficient to compensate for defects in disulfide isomerization.
Pdi1p (protein-disulfide isomerase) is a folding assistant of the endoplasmic reticulum (ER) that catalyzes disulfide formation and the isomerization of incorrect disulfides. Its disulfide forming activity is its essential function in Saccharomyces cerevisiae. A truncation mutant (Pdi1a') that is competent in disulfide formation but deficient in catalyzing isomerization has only a small effect on growth, although the maturation of isomerase-requiring ...
