Anti-MYO9A antibodies are used in the immunodetection of the protein myosin IXA. In humans, the canonical protein has a reported length of 2548 amino acid residues and a mass of 292.7 kDa. Its subcellular localization is in the membrane and cytoplasm. Up to 5 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Myosin protein family, MYO9A is known to be involved with intracellular signal transduction and GPCR signaling pathways. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include unconventional myosin-IXa, unconventional myosin-9a, and CMS24. MYO9A gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some MYO9A antibodies may have been used in research and have associated citations. Immunocytochemistry is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
