Anti-Human CD193 (CCR3) PE

Description: The eBio5E8-G9-B4 monoclonal antibody reacts with human CD193 (CCR3, CKR3). CD193 is a member of the seven transmembrane G-protein coupled receptor (GPCR) family, and is a high affinity chemokine receptor for the chemokines eotaxin-1 (CCL11), eotaxin-2 (CCL24), eotaxin-3 (CCL26) and MCP-4 (CCL13), but has also been reported to bind RANTES, MCP-3 and MCP-4. CD193 is highly expressed on the surface of eosinophils, and is the key eosinophil chemokine receptor responsible for the regulation of eosinophil migration and function. In addition to eosinophils, CD193 is also expressed on CD4+ TH2 cells, basophils, mast cells, mononuclear phagocytes, platelets, CD34+ hematopoietic progenitors and airway epithelial cells. CD193 likely plays an important role in the migration of eosinophils in allergic airway inflammation and asthma. CD193 can also serve as a receptor for HIV-1 cell entry.
