CSH1

mannosylinositol phosphorylceramide synthase catalytic subunit CSH1, YBR161W
Mannosylinositol phosphorylceramide (MIPC) synthase catalytic subunit; forms a complex with regulatory subunit Csg2p; function in sphingolipid biosynthesis is overlapping with that of Sur1p; CSH1 has a paralog, SUR1, 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.

Mannosylinositol phosphorylceramides and ergosterol coodinately maintain cell wall integrity in the yeast Saccharomyces cerevisiae.

Tanaka S, Tani M

In the yeast Saccharomyces cerevisiae, complex sphingolipids have three types of polar head group, and breakdown of their normal composition causes several cellular dysfunctions. Previously we found that loss of biosynthesis of mannosylinositol phosphorylceramide (MIPC) causes a defect in cell wall integrity (CWI). In this study, we screened for multicopy suppressor genes that rescue the defect in CWI in cells ... [more]
