Target Background

Acts as a scavenger receptor on macrophages, which specifically binds to OxLDL (oxidized low density lipoprotein), suggesting that it may be involved in pathophysiology such as atherogenesis. Induces a strong chemotactic response. Induces calcium mobilization. Binds to CXCR6/Bonzo.
