Product Overview:
The family of UBC enzymes plays a central role in the ubiquitin pathway. Genetic studies with the S.cerevisiae Rad6 protein demonstrate a pleiotropic phenotype, including defects in DNA repair, proteolysis of N-end rule protein substrates, cellular proliferation, cell cycle progression and an inability to sporulate, which are all dependent on its ubiquitin-conjugating activity. Rad6 can ubiquitinylate histones in vitro, and ubiquitinylation of histone H2B in S.cerevisiae is Rad6 dependent. In mice and humans, two homologues of RAD6 have been identified - hHR6A (homologue of RAD6A) and hHR6B (homologue of RAD6B). Inactivation of the hHR6B-homologous gene in mice causes male infertility, which strongly implicates hHR6-dependent ubiquitinylation in chromatin remodeling.

Entrez Gene Summary:
The modification of proteins with ubiquitin is an important cellular mechanism for targeting abnormal or short-lived proteins for degradation. Ubiquitination involves at least three classes of enzymes: ubiquitin-activating enzymes, or E1s, ubiquitin-conjugating enzymes, or E2s, and ubiquitin-protein ligases, or E3s. This gene encodes a member of the E2 ubiquitin-conjugating enzyme family. This enzyme is required for post-replicative DNA damage repair. Its protein sequence is 100% identical to the mouse, rat, and rabbit homologs, which indicates that this enzyme is highly conserved in eukaryotic evolution.

UniProt Summary:
FUNCTION: SwissProt: P63146 # Catalyzes the covalent attachment of ubiquitin to other proteins. Required for postreplication repair of UV-damaged DNA. Associates to the E3 ligase RAD18 to form the UBE2B-RAD18 ubiquitin ligase complex involved in mono-ubiquitination of DNA- associated PCNA on 'Lys-164'. May be involved in neurite outgrowth.SIZE: 152 amino acids; 17312 Da SUBUNIT: Interacts with RAD18 and UBR2.SUBCELLULAR LOCATION: Cell membrane (By similarity). Nucleus (By similarity). Note=In peripheral neurons, expressed both at the plasma membrane and in nuclei (By similarity).SIMILARITY: SwissProt: P63146 ## Belongs to the ubiquitin-conjugating enzyme family.
