the study authors (including Stanford geneticist Michael Snyder, PhD) identified more than 2,000 proteins that were activated in MS lesions. One of those proteins, sphingosine-1-phosphate receptor 1, was activated only in the MS brain samples, suggesting its importance in MS pathogenesis.
So I looked up the wikipedia article for that protein, and the protien is called: endothelial differentiation gene 1 (EDG1)
Here's a link to the Wikipedia article about that protein:
Here's an excerpt from the wikipedia page:
Sphingosine-1-phosphate receptor 1 (S1P receptor 1 or S1P1), also known as endothelial differentiation gene 1 (EDG1) is a protein that in humans is encoded the S1PR1 gene. S1PR1 is a G-protein-coupled receptor which binds the bioactive signaling molecule sphingosine 1-phosphate (S1P). S1PR1 belongs to a sphingosine-1-phosphate receptor subfamily comprising five members (S1PR1-5). S1PR1 was originally identified as an abundant transcript in endothelial cells and it has an important role in regulating endothelial cell cytoskeletal structure, migration, capillary-like network formation and vascular maturation. In addition, S1PR1 signaling is important in the regulation of lymphocyte maturation, migration and trafficking.
There's a lot more to the wikipedia article if you go to the link above.
