Specifications

B cell Attracting Chemokine-1 (BCA-1), also known as CXCL13, is expressed at high levels in lymphoid tissues such as the spleen, lymph nodes and Peyerís patches. It has been shown to activate signaling through the receptor BLR1 (Burkittís lymphoma receptor 1) to chemoattract B cells.
