Anti-neuron navigator 1 antibodies are used for the immunodetection of the protein encoded by the NAV1 gene. In humans, the canonical protein has a reported length of 1877 amino acid residues and a mass of 202.5 kDa. Its subcellular localization is in the cytoplasm. Alternative splicing is reported to yield 7 different isoforms for this protein. A member of the Nav/unc-53 protein family, it is suspected to be involved in neuronal migration. Other names for this target antigen include pore membrane and/or filament interacting like protein 3 and unc-53 homolog 1. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of neuron navigator 1 antibodies have been mentioned in research publications and have associated citations. Immunohistochemistry is a widely used application for these antibodies. ELISA, Western Blot, and Immunofluorescence are also common applications.
