概述

C-X-C motif chemokine 13 encoded by the CXCL13 gene located on human chromosome 4 is constitutively expressed in secondary lymphoid organs.It is also known as B lymphocyte chemoattractant(BLC).As its name suggests,CXCL13 is selectively chemotactic for B cells belonging to both the B-1 and B-2 subsets,and elicits its effects by interacting with chemokine receptor CXCR5.It and its receptor CXCR5 control the organization of B cells within follicles of lymphoid tissues.Recombinant human CXCL13 is a single non-glycosylated polypeptide chain containing 87 amino acids and mature human BCA-1 shares 64%amino acid sequence similarity with the murine protein and 23–34%amino acid sequence identity with other known CXC chemokines.
