Phenotypic Suppression

A genetic interaction is inferred when mutation or over expression of one gene results in suppression of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

The Erv41-Erv46 complex serves as a retrograde receptor to retrieve escaped ER proteins.

Shibuya A, Margulis N, Christiano R, Walther TC, Barlowe C

Signal-dependent sorting of proteins in the early secretory pathway is required for dynamic retention of endoplasmic reticulum (ER) and Golgi components. In this study, we identify the Erv41-Erv46 complex as a new retrograde receptor for retrieval of non-HDEL-bearing ER resident proteins. In cells lacking Erv41-Erv46 function, the ER enzyme glucosidase I (Gls1) was mislocalized and degraded in the vacuole. Biochemical ... [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.
