Anti-JAMA antibodies are protein reagents that detect specific antigens. The JAMA antigen is another term for the human protein F11 receptor, encoded by the F11R gene. The protein is believed to play a role in epithelial tight junction formation. Canonically, it has an amino acid length of 299 residues and a mass of 32.6 kilodaltons. Its subcellular localization is in the cell membrane and it is reported to be expressed in endothelium, epithelium and leukocytes. The JAMA protein is a member of the Immunoglobulin protein superfamily. Other alias names for JAMA include CD321, JAM, and JAM1. Western Blot is the most common application for the JAMA antibodies listed below. Flow Cytometry, Immunofluorescence, and Immunohistochemistry are also common applications.
