CC   -!- FUNCTION: Catalyzes the covalent attachment of ubiquitin to other
CC       proteins. Plays a role in transcription regulation by catalyzing the
CC       monoubiquitination of histone H2B to form H2BK123ub1. H2BK123ub1 gives
CC       a specific tag for epigenetic transcriptional activation and is also a
CC       prerequisite for H3K4me and H3K79me formation. Also involved in
CC       postreplication repair of UV-damaged DNA, in N-end rule-dependent
CC       protein degradation and in sporulation. {ECO:0000255|PROSITE-
CC       ProRule:PRU00388}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=S-ubiquitinyl-[E1 ubiquitin-activating enzyme]-L-cysteine +
CC         [E2 ubiquitin-conjugating enzyme]-L-cysteine = [E1 ubiquitin-
CC         activating enzyme]-L-cysteine + S-ubiquitinyl-[E2 ubiquitin-
CC         conjugating enzyme]-L-cysteine.; EC=2.3.2.23;
CC         Evidence={ECO:0000255|PROSITE-ProRule:PRU00388, ECO:0000255|PROSITE-
CC         ProRule:PRU10133};
CC   -!- PATHWAY: Protein modification; protein ubiquitination.
CC       {ECO:0000255|PROSITE-ProRule:PRU00388}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q5VVX9}. Nucleus
CC       {ECO:0000250|UniProtKB:Q5VVX9}.
CC   -!- SIMILARITY: Belongs to the ubiquitin-conjugating enzyme family.
