Function
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 (PubMed:11923095, PubMed:20577214, PubMed:23602659, PubMed:24929359, PubMed:29662056). In contrast to proapoptotic SPHK2, has a negative effect on intracellular ceramide levels, enhances cell growth and inhibits apoptosis (PubMed:16118219). Involved in the regulation of inflammatory response and neuroinflammation. Via the product sphingosine 1-phosphate, stimulates TRAF2 E3 ubiquitin ligase activity, and promotes activation of NF-kappa-B in response to TNF signaling leading to IL17 secretion (PubMed:20577214). In response to TNF and in parallel to NF-kappa-B activation, negatively regulates RANTES induction through p38 MAPK signaling pathway (PubMed:23935096). Involved in endocytic membrane trafficking induced by sphingosine, recruited to dilate endosomes, also plays a role on later stages of endosomal maturation and membrane fusion independently of its kinase activity (PubMed:24929359, PubMed:28049734). In Purkinje cells, seems to be also involved in the regulation of autophagosome-lysosome fusion upon VEGFA (PubMed:25417698). Has serine acetyltransferase activity on PTGS2/COX2 in an acetyl-CoA dependent manner. The acetyltransferase activity increases in presence of the kinase substrate, sphingosine. During neuroinflammation, through PTGS2 acetylation, promotes neuronal secretion of specialized preresolving mediators (SPMs), especially 15-R-lipoxin A4, which results in an increase of phagocytic microglia.

Supplementary info
- This supplementary information is collated from multiple sources and compiled automatically.
- Activity summary
SPHK1 also known as sphingosine kinase 1 is an enzyme that catalyzes the phosphorylation of sphingosine to produce sphingosine-1-phosphate (S1P). This target has a molecular mass of approximately 47 kDa. SPHK1 is expressed in various tissues including the brain spleen heart and lungs. Its activity plays a role in cell signaling processes that are essential for cellular responses to external stimuli.
- Biological function summary
Within the cell SPHK1 participates in regulating cell survival proliferation and inflammation. It is part of the sphingolipid metabolic pathway which is not a traditional protein complex but more of a metabolic sequence. SPHK1 converts sphingosine a lipid signaling molecule into S1P which acts as a ligand for G-protein-coupled receptors. Through this conversion SPHK1 influences diverse cellular functions.
- Pathways
This protein actively participates in the sphingolipid signaling pathway and the apoptosis pathway. In sphingolipid signaling S1P acts alongside ceramide and other sphingolipids to modulate cell response. SPHK1's interplay with the ceramide-sphingosine-S1P rheostat can determine cell fate by tipping the balance towards survival or apoptosis. In the apoptosis pathway SPHK1 serves as a regulator of cell death with its function connected to proteins such as Bcl-2 and Bax which are primary apoptosis regulators.
- Associated diseases and disorders
Abnormal expression of SPHK1 has links to cancer and cardiovascular diseases. In cancer overexpression of SPHK1 contributes to enhanced survival and proliferation of tumor cells with a noted interaction with the protein EGFR which is often upregulated in tumors. In cardiovascular diseases dysregulated SPHK1-S1P signaling can impact vascular integrity and inflammation influencing the progression of atherosclerosis with involvement of other inflammatory proteins like NF-kB.
