SPHK1, along with SPHK2, catalyzes the phosphorylation of sphingosine producing the signaling molecule sphingosine-1-phosphate (S1P). S1P signals through G-protein coupled receptors and controls diverse cellular processes. Inhibitors of SPHKs are viewed as potential therapeutics for the treatment of cancer. SPHK1 catalyzes the phosphorylation of sphingosine to sphingosine 1 phosphate (S1P), an important signaling molecule with intra- and extracellular functions. Inside the cell S1P acts as a signaling molecule like other sphingolipid metabolites like ceramide and sphingosine. S1P has been implicated in regulating cell differentiation, calcium mobilization from intracellular stores, and apoptosis. The cell surface receptors for S1P are the EDG family of G protein-coupled receptors (S1P Receptors).
