Sphingosine-1-phosphate (S1P) is generated through phosphorylation of sphingosine by sphingosine kinases (Sphk1 and Sphk2). We show that <i>sphk2</i> maternal-zygotic mutant zebrafish embryos (<i>sphk2<sup>MZ</sup></i>) display early developmental phenotypes, including a delay in epiboly, depleted S1P levels, elevated levels of sphingosine, and resistance to sphingosine toxicity. The <i>sphk2<sup>MZ</sup></i> embryos also have strikingly increased levels of maternal transcripts encoding ceramide ...[more]
