ROT1

L000003404, YMR200W
Molecular chaperone involved in protein folding in ER; mutation causes defects in cell wall synthesis and lysis of autophagic bodies, suppresses tor2 mutations, and is synthetically lethal with kar2-1 and with rot2 mutations; involved in N-linked glycosylation and O-mannosylation; transmembrane helix Ser250 is essential for Rot1p to interact with other membrane components and exert its functional role, avoiding exposure of Ser H-bonding group at lipid-exposed surface
Saccharomyces cerevisiae (S288c)
PREY

CNE1

FUN48, calnexin, L000000373, YAL058W
Calnexin; integral membrane ER chaperone involved in folding and quality control of glycoproteins; chaperone activity is inhibited by Mpd1p, with which Cne1p interacts; 24% identical to mammalian calnexin; Ca+ binding not yet shown in yeast

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.

Publication

Saccharomyces cerevisiae Rot1p is an ER-localized membrane protein that may function with BiP/Kar2p in protein folding.

Takeuchi M, Kimata Y, Hirata A, Oka M, Kohno K

The 70-kDa heat shock protein (Hsp70) family of molecular chaperones cooperates with cofactors to promote protein folding, assembly of protein complexes and translocation of proteins across membranes. Although many cofactors of cytosolic Hsp70s have been identified, knowledge about cofactors of BiP/Kar2p, an endoplasmic reticulum (ER)-resident Hsp70, is still poor. Here we propose the Saccharomyces cerevisiae protein Rot1p as a possible ... [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.
