Ubiquitin-conjugating enzyme E2 2

Gene

UBC2

Organism
Kluyveromyces lactis (strain ATCC 8585 / CBS 2359 / DSM 70799 / NBRC 1267 / NRRL Y-1140 / WM37) (Yeast) (Candida sphaerica)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

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).PROSITE-ProRule annotation

Catalytic activityi

ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine.PROSITE-ProRule annotation

Pathway: protein ubiquitination

This protein is involved in the pathway protein ubiquitination, which is part of Protein modification.PROSITE-ProRule annotation
