IRE1

ERN1, bifunctional endoribonuclease/protein kinase IRE1, L000000875, YHR079C
Serine-threonine kinase and endoribonuclease; transmembrane protein that mediates the unfolded protein response (UPR) by regulating Hac1p synthesis through HAC1 mRNA splicing; role in homeostatic adaptation to ER stress; Kar2p binds inactive Ire1p and releases from it upon ER stress

ERD2

L000000567, YBL040C
HDEL receptor; an integral membrane protein that binds to the HDEL motif in proteins destined for retention in the endoplasmic reticulum; has a role in maintenance of normal levels of ER-resident proteins

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

Two redundant systems maintain levels of resident proteins within the yeast endoplasmic reticulum.

Beh CT, Rose MD

The Saccharomyces cerevisiae gene ERD2 is responsible for the retrieval of lumenal resident proteins of the endoplasmic reticulum (ER) lost to the next secretory compartment. Previous studies have suggested that the retrieval of proteins by ERD2 is not essential. Here, we find that ERD2-mediated retrieval is not an essential process only because, on its failure, a second inducible system acts ... [more]
