Anti-C-C motif chemokine receptor 7 antibodies are directed against the protein encoded by the gene CCR7 in humans. The gene may also be known as CD197, BLR2, CC-CKR-7, CCR-7, C-C chemokine receptor type 7, and Bukitt's lymphoma receptor 2. Structurally, the protein is reported to be 42.9 kilodaltons in mass. Based on gene name, canine, porcine, monkey, mouse and rat orthologs may also be found.
