Protein Structure
UniProt Annotation
Function Catalyzes the phosphorylation of sphingosine to form sphingosine 1-phosphate (SPP), a lipid mediator with both intra- and extracellular functions. Also acts on D-erythro-sphingosine and to a lesser extent sphinganine, but not other lipids, such as D,L-threo-dihydrosphingosine, N,N-dimethylsphingosine, diacylglycerol, ceramide, or phosphatidylinositol (By similarity). {ECO:0000250}.
Subcellular Localization Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}. Cell membrane {ECO:0000250}. Note=Translocated from the cytoplasm to the plasma membrane in a CIB1-dependent manner. {ECO:0000250}.
