Summaries for SPHK2 Gene

Entrez Gene Summary for SPHK2 Gene

  • This gene encodes one of two sphingosine kinase isozymes that catalyze the phosphorylation of sphingosine into sphingosine 1-phosphate. Sphingosine 1-phosphate mediates many cellular processes including migration, proliferation and apoptosis, and also plays a role in several types of cancer by promoting angiogenesis and tumorigenesis. The encoded protein may play a role in breast cancer proliferation and chemoresistance. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

GeneCards Summary for SPHK2 Gene

SPHK2 (Sphingosine Kinase 2) is a Protein Coding gene. Among its related pathways are Metabolism and Sphingolipid metabolism. GO annotations related to this gene include NAD+ kinase activity and diacylglycerol kinase activity. An important paralog of this gene is AGK.

UniProtKB/Swiss-Prot for SPHK2 Gene

  • 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.

Tocris Summary for SPHK2 Gene

  • Sphingosine kinase (SphK) mediates the conversion of sphingosine to sphingosine-1-phosphate, a key sphingolipid signaling molecule involved in cell growth, survival, differentiation and motility. Two mammalian isoforms have been cloned - SPHK1 and SPHK2.
