UPS2

AIM30, GEP1, MSF1, MSF1', YLR168C
Mitochondrial intermembrane space protein; involved in phospholipid metabolism; has role in regulation of phospholipid metabolism by inhibiting conversion of phosphatidylethanolamine to phosphatidylcholine; null mutant has defects in mitochondrial morphology; similar to Ups1p, Ups3p and to human PRELI; UPS2 has a paralog, UPS3, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)
PREY

UPS3

GEP2, YDR185C
Mitochondrial protein of unknown function; similar to Ups1p and Ups2p which are involved in regulation of mitochondrial cardiolipin and phosphatidylethanolamine levels; null is viable but interacts synthetically with ups1 and ups2 mutations; UPS3 has a paralog, UPS2, that arose from the whole genome duplication

Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.

Distinct Functions of Evolutionary Conserved MSF1 and Late Embryogenesis Abundant (LEA)-like Domains in Mitochondria.

Hall BM, Owens KM, Singh KK

PRELID1, the only late embryogenesis abundant (LEA) domain-containing protein in humans, exerts cytoprotective effects through its LEA domain within the mitochondria. Although PRELID1 homologs in vertebrates contain the LEA domain, homologs in lower eukaryotes are thought to lack this domain. In this study, we identify a novel LEA-like domain in a yeast PRELID1 homolog, Ups2p, which contains sequence conservation with ... [more]
