UPC2

MOX4, YDR213W
Sterol regulatory element binding protein; induces transcription of sterol biosynthetic genes and of DAN/TIR gene products; relocates from intracellular membranes to perinuclear foci on sterol depletion; UPC2 has a paralog, ECM22, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)

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.

Mechanistic role of ergosterol in membrane rigidity and cycloheximide resistance in Saccharomyces cerevisiae.

Abe F, Hiraki T

Mutants of Saccharomyces cerevisiae defective in the late steps of ergosterol biosynthesis are viable but accumulate structurally altered sterols within the plasma membrane. Despite the significance of pleiotropic abnormalities in the erg mutants, little is known about how sterol alterations mechanically affect the membrane structure and correlate with individual mutant phenotypes. Here we demonstrate that the membrane order and occurrence ... [more]
