NCIt definition : Sphingosine kinase 1 (384 aa, 43 kDa) is encoded by the human SPHK1 gene. This protein
plays a role in the phosphorylation of sphingosine.;
NCIt note : Sphingosine kinase 1 catalyzes the conversion of sphingosine to sphingosine-1-phosphate,
which, in turn, mediates signal transduction pathways that regulate cell proliferation,
cell migration, apoptosis and angiogenesis.;
