Alexa Fluor(R) 647 anti-mouse CD193 (CCR3)

CD193, also known as CC-chemokine receptor 3 (CCR3), CC CKR3, MIP1-alpha receptor like-2, and eotaxin receptor, is a member of the G protein-coupled, seven transmembrane receptor family. It binds to the CC chemokines eotaxin, eotaxin-2, and eotaxin-3 with high affinity. CD193 has also been reported to bind RANTES, MCP-3, and MCP-4 with low affinity. CD193 is expressed on mouse eosinophils, basophils, mast cells, mononuclear phagocytes, platelets, hematopoietic progenitor cells, and keratinocytes. It is thought to play a role in allergic diseases such as bronchial asthma and allergic rhinitis. CD193 also function as a co-receptor for HIV-1 and HIV-2, and the binding of eotaxin with CD193 has been shown to inhibit HIV infection in some cell types.
