EDG1 also known as S1P1, S1PR1 is a member of the endothelial differentiation gene (EDG) family of G protein-coupled receptors. EDG1 play a crucial role in mediating the effects of lysophospholipid signaling molecules such as sphingosine-1-phosphate (S1P) and lysophosphatidic acid (LPA). EDG1 is primarily located on the cell surface and is involved in various cellular processes, including cell survival, growth, migration, and differentiation, by coupling to Gi proteins to activate downstream signaling pathways like Akt. This is particularly important in glioma cells, where EDG1 expression is associated with tumor progression and survival. EDG1′s ability to interact with multiple G proteins influences a wide range of physiological responses, making EDG1 a significant target for research in cancer biology and therapeutic development.
