Anti-SPTBN4 antibodies are used in the immunodetection of the protein spectrin beta, non-erythrocytic 4. In humans, the canonical protein has a reported length of 2564 amino acid residues and a mass of 289 kDa. Its subcellular localization is in the cytoplasm. Up to 5 different isoforms have been reported for this protein. It is reported to be expressed in skeletal muscle at the sarcolemma and in the muscle capillaries. A member of the Spectrin protein family, SPTBN4 is known to be involved with cytoskeleton organization and neuronal development. Synonyms for this target antigen include beta-IV spectrin, spectrin beta chain, brain 3, spectrin, non-erythroid beta chain 3, and spectrin beta chain, non-erythrocytic 4. SPTBN4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. A number of SPTBN4 antibodies have been mentioned in research publications and have associated citations. Immunohistochemistry is a widely used application for these antibodies. Western Blot, Immunocytochemistry, and Immunofluorescence are also common applications.
