Anti-FRMD4A antibodies are used in the immunodetection of the protein FERM domain containing 4A. In humans, the canonical protein has a reported length of 1039 amino acid residues and a mass of 115.5 kDa. Its subcellular localization is in the cytoplasm. FRMD4A is reported to be a scaffolding protein that regulates epithelial cell polarity by connecting ARF6 activation with the PAR3 complex (By similarity). The FRMD4A gene has been associated with the disease, Agenesis of the corpus callosum. Synonyms for this target antigen include FERM domain-containing protein 4A and FERM domain containing 4. FRMD4A gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Immunofluorescence is the most common application for the FRMD4A antibodies listed below. Immunocytochemistry and Immunohistochemistry are also common applications.
