Research Abstract

We identified a novel orphan GPCR that reacted specifically with oxidized phospholipids. In this study we further perform biochemical characterization of the GPCR including precise ligand specificity. In addition, we also examine the patho-physiological roles of the GPCR, especially in the development of arteriosclerosis.
