The sphingolipid ceramide is not only a precursor of more complex sphingolipids, but also a potent signaling molecule. Specific ceramide species have distinct cellular functions, and each ceramide synthase therefore has particular roles in cells and organisms. Tidhar and colleagues, utilizing two ceramide synthases differing widely in fatty acid specificity, have identified a short amino acid sequence that is critical for this specificity. This work represents a crucial first step in the understanding of both the enzymology and the biology driving the diverse functions of ceramide.
