PA1-1040 detects S1P1 protein in transfected human and mouse cell samples. This antibody shows no cross-reactivity to S1P3.
PA1-1040 has successfully been used in immuno-fluorescence, immunohistochemistry, immunoprecipitation and Western blot procedures. By Western blot, this antibody detects an ~44 kDa protein representing recombinant S1P1 from transfected HEK293 cells. Immunofluorescence data demonstrates that S1P1 is localized to the plasma membrane after staining with PA1-1040.
The PA1-1040 immunogen is a synthetic peptide corresponding to residues S(359) H P Q K D D G D N P E T I(372) of mouse S1P1. This sequence is completely conserved in rat and 92% conserved in human S1P1. This peptide (Cat. # PEP-220) is available for use in neutralization and control experiments.
S1P1 is a G-protein coupled receptor for the bioactive lysosphingolipid sphingosine 1-phosphate (S1P) that is coupled to the G(i) subclass of heteromeric G proteins. S1P1 signaling leads to the activation of RAC1, SRC, PTK2/FAK1 and MAP kinases. It plays an important role in cell migration via its role in the reorganization of the actin cytoskeleton and formation of lamellipodia in response to stimuli that increase the activity of the sphingosine kinase SPHK1. S1P1 is required for normal chemotaxis toward sphingosine 1-phosphate, normal embryonic heart development, and normal cardiac morphogenesis.
