CXCR5
C-X-C chemokine receptor type 5 (CXC-R5) also known as CD185 (cluster of differentiation 185) or Burkitt lymphoma receptor 1 (BLR1) is a G protein-coupled seven transmembrane receptor for chemokine CXCL13 (also known as BLC) and belongs to the CXC chemokine receptor family. It enables T cells to migrate to lymph node B cell zones. In humans, the CXC-R5 protein is encoded by the CXCR5 gene.[3]
Tissue distribution and function
The BLR1 / CXCR5 gene is specifically expressed in Burkitt's lymphoma and lymphatic tissues, such as follicles in lymph nodes as well as in spleen. The gene plays an essential role in B cell migration.[4] Recently, it was shown that CXCR5 overexpression in breast cancer patients highly correlates with lymph node metastases,[5] and elevated CXCR5 expression may contribute to abnormal cell survival and migration in breast tumors that lack functional p53 protein.[6] Minor allele of SNP rs630923, located in the area of CXCR5 gene promoter and associated with the risk of multiple sclerosis, is responsible for appearance of MEF2C-binding site resulted in reduced CXCR5 gene promoter activity in B-cells during activation, that could lead to decreased autoimmune response [7]
