Tanaka S, Tani M, Mannosylinositol phosphorylceramides and ergosterol coodinately maintain cell wall integrity in the yeast Saccharomyces cerevisiae, FEBS J., DOI: 10.1111/febs.14509, 2018.05, In the yeast Saccharomyces cerevisiae, complex sphingolipids have three types of polar head group, and breakdown of the normal composition causes several cellular dysfunctions. Previously we found that loss of biosynthesis of mannosylinositol phosphorylceramide (MIPC) causes a defect in cell wall integrity. In this study, we screened for multicopy suppressor genes that rescue the defect in cell wall integrity in cells lacking MIPC synthases (Sur1 and Csh1), and found that the defect is partly suppressed by upregulation of ergosterol biosynthesis. In addition, repression of expression of ERG9, which encodes squalene synthase in the ergosterol biosynthesis pathway, in sur1∆ csh1∆ cells caused a strong growth defect and enhancement of the defect in cell wall integrity. The repression of ERG9 and/or the deletion of SUR1 and CSH1 caused an increase in the phosphorylated form of Slt2, a mitogen-activated protein (MAP) kinase activated through impairment of cell wall integrity. Moreover, the deletion of SLT2 or WSC1/2 encoding a sensor protein recognizing cell wall integrity enhanced the growth defect in the ERG9-repressed sur1∆ csh1∆ cells. On the other hand, the ERG9-repressed sur1∆ csh1∆ cells also exhibited an increase in the cell-wall chitin level in a Slt2- and Wsc1/2-independent manner. These results suggested that MIPC and ergosterol are coordinately involved in maintenance of cell wall integrity, and the activation of Slt2 suppress the cell wall integrity defect caused by these metabolic defects..
