Sequence length	168 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Catalyzes the covalent attachment of ubiquitin to other proteins. Plays a role in transcription regulation by catalyzing the monoubiquitination of histone H2B to form H2BK123ub1. H2BK123ub1 gives a specific tag for epigenetic transcriptional activation and is also a prerequisite for H3K4me and H3K79me formation. Also involved in postreplication repair of UV-damaged DNA, in N-end rule-dependent protein degradation and in sporulation By similarity.
Catalytic activity	ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine.
Pathway	Protein modification; protein ubiquitination.
Subcellular location	CytoplasmBy similarity. NucleusBy similarity.
Sequence similarities	Belongs to the ubiquitin-conjugating enzyme family.
