Anti-KPNA5 antibodies are used in the immunodetection of the protein karyopherin subunit alpha 5. In humans, the canonical protein has a reported length of 539 amino acid residues and a mass of 60.7 kDa. Its subcellular localization is in the cytoplasm. It is notably expressed in the testis. A member of the Importin alpha protein family, KPNA5 is reported to function in nuclear protein import as an adapter protein for nuclear receptor KPNB1. Synonyms for this target antigen include SRP6, importin subunit alpha-6, importin alpha 6, karyopherin alpha 5 (importin alpha 6), and IPOA6. KPNA5 gene orthologs have been reported in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species. A number of KPNA5 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, and Immunofluorescence are also common applications.
