Anti-F11R antibodies are used in the immunodetection of the protein F11 receptor. In humans, the canonical protein has a reported length of 299 amino acid residues and a mass of 32.6 kDa. Its subcellular localization is in the cell membrane. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in endothelium, epithelium and leukocytes. A member of the Immunoglobulin protein superfamily, F11R is believed to play a role in epithelial tight junction formation. Post-translational modifications have been described, including N-glycosylation and protein cleavage. Synonyms for this target antigen include JAM, JAM1, JAMA, JCAM, KAT, PAM-1, junctional adhesion molecule A, and CD321. F11R gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 270 citations in the literature describe the use of F11R antibodies in research. Western Blot is a widely used application for these antibodies. Flow Cytometry and Immunohistochemistry are also common applications.
