Identification
NameSphingoid long chain base kinase 5
Synonyms
  • LCB kinase 5
  • Sphinganine kinase 5
Gene NameLCB5
Enzyme Class
Biological Properties
General FunctionInvolved in diacylglycerol kinase activity
Specific FunctionCatalyzes the phosphorylation of the sphingoid long chain bases dihydrosphingosine (DHS or sphinganine) and phytosphingosine (PHS) to form dihydrosphingosine 1-phosphate (DHS-1P) and phytosphingosine 1-phosphate (PHS-1P) respectively. Redundant to LCB4, is only responsible for few percent of the total activity. Involved in the biosynthesis of sphingolipids and ceramides. Involved in heat-induced transient cell cycle arrest. Accumulation of phosphorylated sphingoid long chain bases (LCBPs) stimulates calcium influx and activates calcineurin signaling. Involved in heat-stress resistance
