CXCR5

C-X-C chemokine receptor type 5 (CXC-R5) also known as CD185 (is_associated_with::cluster of differentiation 185) or Burkitt lymphoma receptor 1 (BLR1) is a G protein-coupled seven transmembrane receptor for chemokine is_associated_with::CXCL13 (also known as BLC) and belongs to the CXC chemokine receptor family. In humans, the CXC-R5 protein is encoded by the CXCR5 is_associated_with::gene.

Tissue distribution and function
The BLR1 / CXCR5 is_associated_with::gene is specifically expressed in is_associated_with::Burkitt's lymphoma and lymphatic tissues, such as follicles in is_associated_with::lymph nodes as well as in is_associated_with::spleen. The gene plays an essential role in is_associated_with::B cell migration.
