Sphinganine (d18:0) is a precursor of ceramide and sphingosine as well as a substrate of sphingosine kinases, which generate sphinganine-1-phosphate. Sphinganine levels increase significantly in response to certain mycotoxins, including fumonisins,[1,2] as well as in some cancers.[3] Sphinganine can block protein kinase C activation in some cases but not others.[4,5] Sphinganine-1-phosphate can emulate sphingosine-1-phosphate in cell signaling or have opposite intracellular effects.[6,7,8]
