Specificity: This Polyclonal antibody is directed against human LPA 1 protein. The product was purified from seurm by protein A chromatography. Cross-reactivity with LPA 1 from other sources has not been determined.Relevance: LPA 1 (also known as EDG-2) is one of four known lysophosphatidic acid (LPA) receptors (LPA 1-4).LPA1-3 are part a family of G protein-coupled receptors that share identity to the sphingosine-1-phosphate receptors (S1P 1-5 )(1). LPA 1 couples with three types of G proteins, G i/o, G q, and G 12/13 to induce a range of cellular responses including activation of phospholipase C, multiple kinases, the serum response element and cell proliferation(2,3). LPA 1 mRNA is detected a wide range of tissues and cells including brain, heart, small intestine, spleen, testis, kidney, HeLa cells, and A549 cells(4,5). Murine and human LPA 1 have 364 amino acids with an estimated molecular weight of 41 kDa(3). Us LPA 1 polyclonal antibody detects the protein from several species from 43-50 kDa, suggesting heterogeneous LPA1 post-translational modifications in distinct cells.
