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)
PREY

SYS1

L000004153, YJL004C
Integral membrane protein of the Golgi; required for targeting of the Arf-like GTPase Arl3p to the Golgi; multicopy suppressor of ypt6 null mutation
Saccharomyces cerevisiae (S288c)

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.

Synthesis of mannosylinositol phosphorylceramides is involved in maintenance of cell integrity of yeast Saccharomyces cerevisiae.

Morimoto Y, Tani M

Complex sphingolipids play important roles in many physiologically important events in yeast Saccharomyces cerevisiae. In this study, we screened yeast mutant strains showing a synthetic lethal interaction with loss of mannosylinositol phosphorylceramide (MIPC) synthesis and found that a specific group of glycosyltransferases involved in the synthesis of mannan-type N-glycans is essential for the growth of cells lacking MIPC synthases (Sur1 ...
