Anti-SETMAR antibodies are used in the immunodetection of the protein SET domain and mariner transposase fusion gene. In humans, the canonical protein has a reported length of 684 amino acid residues and a mass of 78 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. It is found to be widely expressed, with highest expression in the placenta and ovary and lowest expression in skeletal muscle. A member of the Mariner transposase protein family, SETMAR is known to be involved with cell proliferation and chromatin organization. Synonyms for this target antigen include histone-lysine N-methyltransferase SETMAR, SET domain and mariner transposase fusion gene-containing protein, SET domain and mariner transposase fusion protein, and METNASE. SETMAR gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of SETMAR antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
