Anti-UBE2D4 antibodies are used in the immunodetection of the protein ubiquitin conjugating enzyme E2 D4 (putative). In humans, the canonical protein has a reported length of 147 amino acid residues and a mass of 16.6 kDa. It is notably expressed in many tissues, such as the bone marrow, urinary bladder, and adipose tissue. A member of the Ubiquitin-conjugating enzyme protein family, UBE2D4 is known to accept ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. Synonyms for this target antigen include ubiquitin-conjugating enzyme E2 D4, E2 ubiquitin-conjugating enzyme D4, ubiquitin carrier protein D4, ubiquitin-conjugating enzyme HBUCE1, ubiquitin-protein ligase D4, and HBUCE1. UBE2D4 gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. Some UBE2D4 antibodies may have been used in research and have associated citations. ELISA is a widely used application for these antibodies. In addition, Western Blot is also a common application.
