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

MDM31

YHR194W
Mitochondrial protein that may have a role in phospholipid metabolism; inner membrane protein with similarity to Mdm32p; required for normal mitochondrial morphology and inheritance; interacts genetically with MMM1, MMM2, MDM10, MDM12, and MDM34

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.

Role for two conserved intermembrane space proteins, Ups1p and Up2p, in intra-mitochondrial phospholipid trafficking.

Tamura Y, Onguka O, Aiken Hobbs AE, Jensen RE, Iijima M, Claypool SM, Sesaki H

Mitochondrial membranes maintain a specific phospholipid composition. Most phospholipids are synthesized in the endoplasmic reticulum (ER) and transported to mitochondria, while cardiolipin and phosphatidylethanolamine are produced in mitochondria. In the yeast Saccharomyces cerevisiae, phospholipid exchange between the ER and mitochondria relies on the ER-mitochondria encounter structure (ERMES) complex, which physically connects the ER and mitochondrial outer membrane. However, the proteins ... [more]
