Anti-SUMO4 antibodies are used in the immunodetection of the protein small ubiquitin like modifier 4. In humans, the canonical protein has a reported length of 95 amino acid residues and a mass of 10.7 kDa. It is notably expressed in adult and embryonic kidney. A member of the Ubiquitin protein family, SUMO4 is reported to be a ubiquitin-like protein, which can be covalently attached to target lysines as a monomer. The SUMO4 gene has been associated with the disease, Type 1 diabetes mellitus. Synonyms for this target antigen include SMT3 suppressor of mif two 3 homolog 2, SMT3 suppressor of mif two 3 homolog 4, insulin-dependent diabetes mellitus 5, small ubiquitin-like modifier 4 protein, and small ubiquitin-related modifier 4. SUMO4 gene orthologs have been reported in the mouse, rat and chimpanzee species. A number of SUMO4 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
