CDC34

CDC34 is a gene that in humans encodes the protein Ubiquitin-conjugating enzyme E2 R1.^[5][6][7] This protein is a member of the ubiquitin-conjugating enzyme family, which catalyzes the covalent attachment of ubiquitin to other proteins.^[8]

CDC34 was originally discovered by work in baker's yeast as a gene that is essential for the cell cycle.^[9] Cdc34 in yeast targets numerous substrates - notably the cyclin-dependent kinase inhibitor Sic1^[10] - for ubiquitin-mediated protein degradation.^[11] CDC34 is required for ubiquitin-mediated degradation of cell cycle G1 regulators, and for the initiation of DNA replication.^[7]
