EDG-6 is a member of the endothelial differentiation gene (EDG) G protein-coupled receptor family and is a receptor for sphingosine 1-phosphate (S1P). Binding of S1P to EDG-6 activates Erk, leading to the activation of the transcription factor Elk1 and thus the mitogen-activated protein kinase (MAPK) signal transduction pathway. The protein is specifically expressed in fetal and adult lymphoid and hematopoietic tissue as well as in lung. Human EDG-6 gene is intronless and is mapped to chromosome 19p13.3 at the D19S120 marker.WARNING This product is not for human or veterinary use.
