Anti-CDC34 antibodies are used in the immunodetection of the protein cell division cycle 34, ubiqiutin conjugating enzyme. In humans, the canonical protein has a reported length of 236 amino acid residues and a mass of 26.7 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is reported to be expressed in testes during spermatogenesis to regulate repression of cAMP-induced transcription. A member of the Ubiquitin-conjugating enzyme protein family, CDC34 is known to accept ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. Synonyms for this target antigen include UBC3, UBCH3, UBE2R1, ubiquitin-conjugating enzyme E2 R1, (E3-independent) E2 ubiquitin-conjugating enzyme R1, and E2-CDC34. CDC34 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of CDC34 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.
