Anti-SUV39H2 antibodies are used in the immunodetection of the protein SUV39H2 histone lysine methyltransferase. In humans, the canonical protein has a reported length of 410 amino acid residues and a mass of 46.7 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. It is notably expressed in the testis. A member of the Histone-lysine methyltransferase protein family, SUV39H2 is a known histone methyltransferase that specifically trimethylates 'Lys-9' of histone H3 using monomethylated H3 'Lys-9' as substrate. Post-translational modifications have been described, including ubiquitination. Synonyms for this target antigen include H3-K9-HMTase 2, histone H3-K9 methyltransferase 2, histone methyltransferase SUV39H2, lysine N-methyltransferase 1B, and histone-lysine N-methyltransferase SUV39H2. SUV39H2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of SUV39H2 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.
