Anti-SUMO2 antibodies are used in the immunodetection of the protein small ubiquitin like modifier 2. In humans, the canonical protein has a reported length of 95 amino acid residues and a mass of 10.9 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the Ubiquitin protein family, SUMO2 is reported to be a ubiquitin-like protein that can be covalently attached to proteins as a monomer or as a lysine-linked polymer. Synonyms for this target antigen include SMT3B, SMT3H2, SUMO3, Smt3A, small ubiquitin-related modifier 2, and HSMT3. SUMO2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 150 citations in the literature describe the use of SUMO2 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
