CXCR5 Antibody / BLR1 / MDR15

Chemokine CXC Motif Receptor 5, also known as BLR1 and MDR15, is a G protein-coupled seven transmembrane receptor for chemokine CXCL13 (also known as BLC) and belongs to the CXC chemokine receptor family. In humans, the protein is encoded by the CXCR5 gene. The gene plays an essential role in B cell migration. Reif et al. (2002) concluded that their findings defined the mechanism of B-cell relocalization in response to antigen, and established that cell position in vivo can be determined by the balance of responsiveness to chemoattractants made in separate but adjacent zones. Chan et al. (2003) investigated the expression of chemokines and chemokine receptors in eyes with primary intraocular B-cell lymphoma (PIOL) .
