Anti-Importin 4 antibodies are used for the immunodetection of the protein encoded by the IPO4 gene. In humans, the canonical protein has a reported length of 1081 amino acid residues and a mass of 118.7 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. It is a member of the Importin beta protein family. Other names for this target antigen include importin-4b, ran-binding protein 4, ranBP4, and imp4b. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of Importin 4 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
