Application
Sphingosine kinase 1 has been used in a study to assess the modulation of cellular S1P levels. Sphingosine kinase 1 has also been used in a study to investigate how FTY720 normalizes hyperglycemia.
Biochem/physiol Actions
Converts sphingosine to sphingosine-1-phosphate. SPHK1 shares two large conserved regions with SPHK2. While SPHK1 is found only in the cytosol, SPHK2 is localized in both the cytosol and nuclei.
General description
Sphingosine 1-phosphate-induced release of TIMP-2 from vascular smooth muscle cells inhibits angiogenesis.
