Anti-embigin antibodies are used for the immunodetection of the protein encoded by the EMB gene. In humans, the canonical protein has a reported length of 327 amino acid residues and a mass of 36.9 kDa. Its subcellular localization is in the cell membrane. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to play a role in the outgrowth of motoneurons and in the formation of neuromuscular junctions. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include embigin homolog. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. These embigin antibodies are widely used in Western Blot experiments, among other applications.
