ECM22

L000004375, YLR228C
Sterol regulatory element binding protein; regulates transcription of sterol biosynthetic genes; contains Zn[2]-Cys[6] binuclear cluster; relocates from intracellular membranes to perinuclear foci on sterol depletion; ECM22 has a paralog, UPC2, that arose from the whole genome duplication

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.

A mutation in sphingolipid synthesis suppresses defects in yeast ergosterol metabolism.

Valachovic M, Wilcox LI, Sturley SL, Bard M

A mutation in an otherwise nonessential ERG2 gene is synthetically lethal when combined with mutations in two transcription factors encoded by the UPC2 and ECM22 genes. Employing UV mutagenesis, we isolated a suppressor of the triple mutant erg2delta upc2delta ecm22delta. The morpholine-resistant phenotype of the suppressor was used to identify the suppressor as a mutation in the ELO3 gene. In ... [more]
