Protein attributes

Sequence length	167 AA.
Sequence status	Complete.
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	Cytoplasm By similarity. Nucleus By similarity.
Sequence similarities	Belongs to the ubiquitin-conjugating enzyme family.
