The regulation of sphingosine-1-phosphate metabolism

4122 | Oct 20 2011

Sphingosine-1-phosphate (S1P) is a signaling sphingolipid and is also referred to as a bioactive lipid mediator. Functions of S1P are mediated by its binding to a class of G-protein coupled receptors of the S1P and Lysophospholipid (LPA) receptor families, and regulate a variety of cell signaling pathways, including cell growth, differentiation, survival, and apoptosis. Many factors in the metabolism pathway of S1P have been considered as potential targets for therapeutic intervention, including the inhibition of S1P activation of the G-protein coupled receptors.
