Anti-Moesin antibodies are used for the immunodetection of the protein encoded by the MSN gene. In humans, the canonical protein has a reported length of 577 amino acid residues and a mass of 67.8 kDa. Its subcellular localization is in the cell membrane. It is noted to be involved in the regulation of gene expression. Post-translational modifications have been described, including phosphorylation. The gene encoding this protein is implicated in Immunodeficiency. Other names for this target antigen include IMD50, epididymis luminal protein 70, membrane-organizing extension spike protein, and HEL70. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 440 citations in the literature describe the use of Moesin antibodies in research. Western Blot is a widely used application for these antibodies. Flow Cytometry, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
