Background
Edg2, a Lysophospholipid/Lysosphingolipid Receptor, mediates growth factor-like activities such as proliferation, platelet aggregation, and chemotaxis. Edg2 is involved in myelin formation or maintenance. It is activated by platelet-derived lysophosphatidic acid (LPA), a lipid metabolite present in serum that acts ubiquitously. Although alternate translation start codons and polyadenylation sites have been reported, the alternative splicing transcripts each encode identical proteins. Edg2 has been reported in most human tissues, and is especially abundant in brain cortical regions. ESTs have been isolated from bone, brain, breast, connective tissue, embryo, heart/melanocyte/uterus, lung, prostate, and uterus libraries. |
