Anti-UBR2 antibodies are used in the immunodetection of the protein ubiquitin protein ligase E3 component n-recognin 2. In humans, the canonical protein has a reported length of 1755 amino acid residues and a mass of 200.5 kDa. Its subcellular localization is in the nucleus. Up to 4 different isoforms have been reported for this protein. It is widely expressed across many tissues, with highest levels in skeletal muscle, kidney and pancreas. A member of the UBR1 protein family, UBR2 is known to be involved with spermatogenesis. Synonyms for this target antigen include bA49A4.1, dJ242G1.1, dJ392M17.3, E3 ubiquitin-protein ligase UBR2, RING-type E3 ubiquitin transferase UBR2, and C6orf133. UBR2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of UBR2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
