Anti-CCG-B7 antibodies are protein reagents that detect specific antigens. The CCG-B7 antigen is another term for the human protein tetraspanin 7, encoded by the TSPAN7 gene. The protein is suspected to be involved in cell proliferation and cell motility. Canonically, it has an amino acid length of 249 residues and a mass of 27.6 kilodaltons. Its subcellular localization is in the membrane and it is expressed in many tissues, such as the colon and duodenum. The CCG-B7 protein is a member of the Tetraspanin (TM4SF) protein family. Other alias names for CCG-B7 include A15 and CD231.
