Protein

Ubiquitin carboxyl-terminal hydrolase 4

Gene

DOA4

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

Ubiquitin thioesterase that acts at the late endosome/prevacuolar compartment to recover ubiquitin from ubiquitinated membrane proteins en route to the vacuole. Removes also ubiquitin from soluble proteins targeted to proteasomes. Is essential to maintain a normal level of free ubiquitin. Involved in the ammonium-induced down-regulation of the GAP1 permease and the UME3 destruction in response to oxidative stress. Has a role in the RAD9 checkpoint response to TOP1 poisons. Required for promoting coordination of DNA replication and avoids DNA overreplication.19 Publications

Miscellaneous

Present with 428 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).

Enzyme regulationi

RFU1 is an inhibitor of deubiquitination activity.1 Publication
