VMA2

VAT2, H(+)-transporting V1 sector ATPase subunit B, ATPSV, L000002458, YBR127C
Subunit B of V1 peripheral membrane domain of vacuolar H+-ATPase; an electrogenic proton pump found throughout the endomembrane system; contains nucleotide binding sites; also detected in the cytoplasm; protein abundance increases in response to DNA replication stress
Saccharomyces cerevisiae (S288c)
PREY

SUR1

BCL21, CSG1, LPE15, mannosylinositol phosphorylceramide synthase catalytic subunit SUR1, L000002243, YPL057C
Mannosylinositol phosphorylceramide (MIPC) synthase catalytic subunit; forms a complex with regulatory subunit Csg2p; function in sphingolipid biosynthesis is overlapping with that of Csh1p; SUR1 has a paralog, CSH1, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)

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.

Alteration of complex sphingolipid composition and its physiological significance in yeast Saccharomyces cerevisiae lacking vacuolar ATPase.

Tani M, Toume M

In the yeast Saccharomyces cerevisiae, complex sphingolipids have three types of polar head group and five types of ceramide; however, the physiological significance of the structural diversity is not fully understood. Here, we report that deletion of vacuolar H+-ATPase (V-ATPase) in yeast causes dramatic alteration of the complex sphingolipid composition, which includes decreases in hydroxylation at the C-4 position of ...
