Protein
Sphingosine kinase 1
Gene
Sphk1
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

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.

Catalytic activityi

ATP + sphinganine = ADP + sphinganine 1-phosphate.
ATP + sphingosine = ADP + sphingosine 1-phosphate.

Cofactori

Magnesium By similarity.
