Anti-UBA2 antibodies are used in the immunodetection of the protein ubiquitin like modifier activating enzyme 2. In humans, the canonical protein has a reported length of 640 amino acid residues and a mass of 71.2 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. It is a member of the Ubiquitin-activating E1 protein family. Post-translational modifications have been described, including sumoylation. Synonyms for this target antigen include ARX, HRIHFB2115, SAE2, SUMO-activating enzyme subunit 2, SUMO-1 activating enzyme subunit 2, and ACCES. UBA2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of UBA2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
