A lipid enzyme called sphingosine kinase (SphK1 and SphK2) catalyzes the phosphorylation of sphingosine to create sphingosine 1-phosphate (S1P). Mammalian organisms have two SphK isoforms, SphK1 and SphK2. SphK1 is primarily present in the cytoplasm and plasma membrane of mast, endothelial, and erythrocyte cells. SphK2 is bigger and is concentrated in the mitochondria, endoplasmic reticulum, and nucleus.
Sphingosine 1-phosphate (S1P) can control intracellular target proteins by binding to five different sphingosine 1-phosphate receptors on the plasma membrane (S1P1–5). S1P performs a wide range of biological activities, including promoting cellular survival and proliferation, moving immune cells, promoting angiogenesis, and controlling vascular integrity. Accumulation of S1P has been associated with cancer development/progression as well as a number of other illnesses, such as inflammatory bowel disease, rheumatoid arthritis, asthma, and diabetic nephropathy. As a result, the biosynthetic pathway for S1P is an obvious candidate for drug discovery. The isozymes SphK1 and SphK2 are also acknowledged therapeutic targets.
