Sphingosine kinases (SPHKs) catalyze the phosphorylation of sphingosine to form sphingosine-1-phosphate (S1P), a lipid mediator with both intra- and extracellular functions. Together with other sphingolipid metabolizing enzymes, SPHKs regulate the balance of the lipid mediators, ceramide, sphingosine, and S1P (1-4). Two distinct SPHK isoforms, SPHK1 and SPHK2, have been cloned and characterized (5,6). SPHK1 and SPHK2 are highly conserved and diversely expressed (7,8). The SPHKs are activated by G protein-coupled receptors, receptor tyrosine kinases, immunoglobulin receptors, cytokines, and other stimuli (9-12). The molecular mechanisms by which SPHK1 and SPHK2 are specifically regulated are complex and only partially understood.

鞘氨醇激酶(SPHKs)催化鞘氨醇磷酸化形成鞘氨醇-1 - 磷酸(S1P),作为细胞内和细胞外功能的脂质载体。与其他的神经鞘脂代谢酶一样,SPHKs调节脂质载体、神经酰胺、鞘氨醇和S1P的平衡(1-4)。已经克隆和阐明两个截然不同的SPHK亚型,SPHK1和SPHK2(5,6)。SPHK1 和 SPHK2高度保守并广泛表达(7,8)。SPHKs都是由G蛋白偶联受体、受体酪氨酸激酶、免疫球蛋白受体、细胞因子和其他刺激物激活(9-12)。通过SphK1和SPHK2特异性调节的分子机制是复杂的,仅有部分已有阐述。
