Anti-PRMT9 antibodies are used in the immunodetection of the protein protein arginine methyltransferase 9. In humans, the canonical protein has a reported length of 845 amino acid residues and a mass of 94.5 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. A member of the Protein arginine N-methyltransferase protein family, PRMT9 is reported to be an arginine methyltransferase that can both catalyze the formation of omega-N monomethylarginine (MMA) and symmetrical dimethylarginine (sDMA). Synonyms for this target antigen include protein arginine N-methyltransferase 10, protein arginine methyltransferase 10 (putative), putative protein arginine N-methyltransferase 10, and protein arginine N-methyltransferase 9. PRMT9 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some PRMT9 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
