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

MNN2

CRV4, LDB8, TTP1, L000002385, YBR015C
Alpha-1,2-mannosyltransferase; responsible for addition of the first alpha-1,2-linked mannose to form the branches on the mannan backbone of oligosaccharides, localizes to an early Golgi compartment

Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Publication

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 ...
