|Function||Accepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. In association with the E3 enzyme BRE1 (RNF20 and/or RNF40), it plays a role in transcription regulation by catalyzing the monoubiquitination of histone H2B at 'Lys-120' to form H2BK120ub1. H2BK120ub1 gives a specific tag for epigenetic transcriptional activation, elongation by RNA polymerase II, telomeric silencing, and is also a prerequisite for H3K4me and H3K79me formation. In vitro catalyzes 'Lys-11'-, as well as 'Lys-48'- and 'Lys-63'-linked polyubiquitination. 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.|
|Cellular Location||Cell membrane. Nucleus. Note=In peripheral neurons, expressed both at the plasma membrane and in nuclei.|

The modification of proteins with ubiquitin is animportant cellular mechanism for targeting abnormal or short-livedproteins for degradation. Ubiquitination involves at least threeclasses of enzymes: ubiquitin-activating enzymes, or E1s,ubiquitin-conjugating enzymes, or E2s, and ubiquitin-proteinligases, or E3s. This gene encodes a member of the E2ubiquitin-conjugating enzyme family. This enzyme is required forpost-replicative DNA damage repair. Its protein sequence is 100%identical to the mouse, rat, and rabbit homologs, which indicatesthat this enzyme is highly conserved in eukaryotic evolution.
