Induces a strong chemotactic response. Induces calcium mobilization. Binds to CXCR6/Bonzo. Also 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. Widely expressed. Not detected in purified B- and T-cells. Glycosylated. Belongs to the intercrine alpha (chemokine CxC) family.
