| In vitro study | S1P (1 μM) induces a significant Ca 2+ releases in HEK293 cells under serum starvation conditions (1% FCS).In a functional Ca 2+ assay, Suramin (HY-B0879) alone does not exert any effect on intracellular Ca 2+ release via gpr3, gpr6 or gpr12. In contrast, S1P (1 μM) induces Ca 2+ release of gpr3, gpr6 and gpr12 in the presence of Suramin (HY-B0879) various concentrations in transfected HEK293 cells. In a functional Ca 2+ assay,S1P (3-3000 nM) in the presence Suramin (300 μM), exhibits nanomolar EC 50 values for gpr3 (EC 50 =29 nM), gpr6 (EC 50 =15 nM) and gpr12 (EC 50 =24 nM), rat gpr3 (EC 50 =68 nM),respectively in HEK293 cells. S1P increases intracellular calcium levels in TAg-Jurkat cells expressing S1P1and G qi5 , which allows for phospholipase C stimulation by G i proteins, when used at a concentration of 200 nM, as well as in TAg-Jurkat cells expressing S1P2and S1P3receptors (EC 50 s = 8 and 11 nM, respectively). |

Protein A - Reference Information
| biological activity | Sphingosine-1-phosphate (S1P) is a S1P1-5 receptor (S1P1-5 receptors) agonist and GPR3, GPR6, ligand for gpr12. Sphingosine-1-phosphate is an intracellular second messenger that mobilizes Ca2 as an extracellular ligand for G protein-coupled receptors. Sphingosine-1-phosphate is an important lipid mediator produced by sphingomyelin (HY-113498) or other membrane phospholipids. |
