Anti-PNMA family member 3 antibodies are used for the immunodetection of the protein encoded by the PNMA3 gene. In humans, the canonical protein has a reported length of 463 amino acid residues and a mass of 52.4 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 2 different isoforms for this protein. It is notably expressed at high levels in the brain and testis. A member of the PNMA protein family, it is known to be involved with the regulation of apoptosis. Other names for this target antigen include MA5, paraneoplastic antigen Ma3, paraneoplastic Ma antigen 3, paraneoplastic cancer-testis-brain antigen, and MA3. Gene orthologs have been identified in the mouse, rat and chimpanzee species. Western Blot is a widely used application for the PNMA family member 3 antibodies listed below. In addition, Immunohistochemistry is also a common application.
