Phenotypic Enhancement

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

Publication

Hydroxylation state of fatty acid and long-chain base moieties of sphingolipid determine the sensitivity to growth inhibition due to AUR1 repression in Saccharomyces cerevisiae.

Tani M, Kuge O

The structures of ceramide found in the yeast Saccharomyces cerevisiae are classified into five groups according to the hydroxylation states of the long-chain base and fatty acid moieties. This diversity is created through the action of enzymes encoded by SUR2, SCS7, and as yet unidentified hydroxylation enzyme(s). Aur1p is an enzyme catalyzing the formation of inositol phosphorylceramide in the yeast, ... [more]
