  "summary": "Ceramides are precursors of complex sphingolipids and bioactive membrane lipids. In the fission yeast Schizosaccharomyces pombe, they are produced by a ceramide synthase with two catalytic subunits, Lac1 and Lag1, which are redundant but not functionally equivalent: only Lac1 is required for normal growth and cell size. Why Lac1 has this unique role, and how ceramide synthesis contributes to cell…",
