| Activity Regulation | ACTIVITY REGULATION: RFU1 is an inhibitor of deubiquitination activity. {ECO:0000250}. |
| Binding Site | |
| Calcium Binding | |
| catalytic Activity | CATALYTIC ACTIVITY: Reaction=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).; EC=3.4.19.12; |
| DNA Binding | |
| EC Number | 3.4.19.12 |
| Enzyme Function | FUNCTION: 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 (By similarity). {ECO:0000250}. |
