Anti-nucleoporin 43 antibodies are used for the immunodetection of the protein encoded by the NUP43 gene. In humans, the canonical protein has a reported length of 380 amino acid residues and a mass of 42.2 kDa. Its subcellular localization is in the nucleus and chromosomes. Alternative splicing is reported to yield 2 different isoforms for this protein. It is a known component of the Nup107-160 subcomplex of the nuclear pore complex (NPC). Other names for this target antigen include nucleoporin 43kDa, nup107-160 subcomplex subunit Nup43, and nucleoporin Nup43. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some nucleoporin 43 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
