Anti-UBE2Q2 antibodies are used in the immunodetection of the protein ubiquitin conjugating enzyme E2 Q2. In humans, the canonical protein has a reported length of 375 amino acid residues and a mass of 42.8 kDa. Its subcellular localization is in the cytoplasm. Up to 4 different isoforms have been reported for this protein. It is notably expressed in hypopharyngeal head and neck squamous cell carcinoma, in tumor masses and invasive epithelium. A member of the Ubiquitin-conjugating enzyme protein family, UBE2Q2 is known to accept ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. Post-translational modifications have been described, including ubiquitination. Synonyms for this target antigen include ubiquitin carrier protein Q2, ubiquitin conjugating enzyme E2Q family member 2, ubiquitin-protein ligase Q2, and E2 ubiquitin-conjugating enzyme Q2. UBE2Q2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some UBE2Q2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
