Protein

Ubiquitin thioesterase OTU1

Gene

OTU1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Hydrolase that can remove conjugated ubiquitin from proteins and may therefore play an important regulatory role at the level of protein turnover by preventing degradation. Participates in the regulation of the ubiquin conjugation pathway involving CDC48 by hindering multiubiquitination of substrates at the CDC48 chaperone. May be indireclty involved in PIS1 gene expression.2 Publications

Miscellaneous

Present with 2770 molecules/cell in log phase SD medium.1 Publication

Catalytic activityi

Thiol-dependent hydrolysis of ester, thioester, amide, peptide and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76-residue protein attached to proteins as an intracellular targeting signal).By similarity
