9.A.14.2.1
Sphingosine 1-phosphate receptor, Edg1, Edg-1, CHEDG1 or S1PR1. The 3-d structure in known (Hanson et al., 2012). The activation mechanism has been proposed (Caliman et al. 2017). It plays an important role in cell migration, probably via its role in the reorganization of the actin cytoskeleton and the formation of lamellipodia in response to stimuli that increase the activity of the sphingosine kinase, SPHK1. It is also required for normal chemotaxis toward sphingosine 1-phosphate. Finally it is involved in responses to oxidized 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphocholine by pulmonary endothelial cells (Singleton et al. 2009; Hanson et al. 2012).
