Supplementary information

SPHK2 also known as sphingosine kinase 2 is an enzyme responsible for the conversion of sphingosine to sphingosine-1-phosphate (S1P). This enzyme weighs approximately 68 kDa and is expressed in a wide range of tissues including liver kidney and brain. The catalytic activity of SPHK2 involves the phosphorylation of sphingosine which plays a part in the modulation of various cellular processes.
Biological function summary

SPHK2 influences cell growth survival and differentiation by generating sphingosine-1-phosphate a signaling lipid. It functions independently or in association with other proteins but it is not always a part of a larger complex. The generated S1P acts as a signaling molecule both inside and outside of cells affecting processes like apoptosis and inflammation.

Pathways

SPHK2 is a significant player in the sphingolipid signaling pathway and impacts the MAPK/ERK pathway. These pathways collectively regulate cellular proliferation and apoptosis. SPHK2 works in conjunction with SPHK1 a closely related sphingosine kinase in these signaling routes. These kinases together help to balance the levels of sphingosine and S1P which is essential for maintaining cellular homeostasis.

SPHK2 has been linked to cancer and inflammatory diseases. The overexpression of SPHK2 can result in increased levels of sphingosine-1-phosphate promoting cancer cell survival and resistance to chemotherapy. In addition SPHK2's involvement in inflammation suggests roles in conditions like rheumatoid arthritis where it might interact with TNF-α related signaling pathways. These connections highlight SPHK2 as a potential target for therapeutic intervention in such diseases.

Target data

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-dihydrosphingosine, D-erythro-sphingosine and L-threo-dihydrosphingosine. Binds phosphoinositides (PubMed : 12954646, PubMed : 19168031). In contrast to prosurvival SPHK1, has a positive effect on intracellular ceramide levels, inhibits cells growth and enhances apoptosis (PubMed : 16118219). In mitochondria, is important for cytochrome-c oxidase assembly and mitochondrial respiration. The SPP produced in mitochondria binds PHB2 and modulates the regulation via PHB2 of complex IV assembly and respiration (PubMed : 20959514). In nucleus, plays a role in epigenetic regulation of gene expression. Interacts with HDAC1 and HDAC2 and, through SPP production, inhibits their enzymatic activity, preventing the removal of acetyl groups from lysine residues with histones. Up-regulates acetylation of histone H3-K9, histone H4-K5 and histone H2B-K12 (PubMed : 19729656). In nucleus, may have an inhibitory effect on DNA synthesis and cell cycle (PubMed : 12954646, PubMed : 16103110). In mast cells, is the main regulator of SPP production which mediates calcium influx, NF-kappa-B activation, cytokine production, such as TNF and IL6, and degranulation of mast cells (By similarity). In dopaminergic neurons, is involved in promoting mitochondrial functions regulating ATP and ROS levels (By similarity). Also involved in the regulation of glucose and lipid metabolism (By similarity).
