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, ECO:0000269|PubMed:10712706}.
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 -!- INDUCTION: Up-regulated by UV radiation, heat shock, osmotic stress and
CC nitrogen starvation. {ECO:0000269|PubMed:10712706}.
CC -!- SIMILARITY: Belongs to the ubiquitin-conjugating enzyme family.
CC {ECO:0000255|PROSITE-ProRule:PRU00388}.
