ERI1

RIN1, S000028417, YPL096C-A
Endoplasmic reticulum membrane protein that binds and inhibits Ras2p; binds to and inhibits GTP-bound Ras2p at the endoplasmic reticulum (ER); component of the GPI-GnT complex which catalyzes the first step in GPI-anchor biosynthesis; probable homolog of mammalian PIG-Y protein

GFA1

glutamine--fructose-6-phosphate transaminase (isomerizing) GFA1, L000000702, YKL104C
Glutamine-fructose-6-phosphate amidotransferase; catalyzes the formation of glucosamine-6-P and glutamate from fructose-6-P and glutamine in the first step of chitin biosynthesis; GFA1 has a paralogous region, comprising ORFs YMR084W-YMR085W, that arose from the whole genome duplication

Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

Yeast Ras regulates the complex that catalyzes the first step in GPI-anchor biosynthesis at the ER.

The yeast ERI1 gene encodes a small ER-localized protein that associates in vivo with GTP bound Ras2 in an effector loop-dependent manner. We showed previously that loss of Eri1 function results in hyperactive Ras phenotypes. Here, we demonstrate that Eri1 is a component of the GPI-GlcNAc transferase (GPI-GnT) complex in the ER, which catalyzes transfer of GlcNAc from UDP-GlcNAc to ... [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.
