General annotation (Comments)

Function

Ubiquitin-protein hydrolase involved both in the processing of ubiquitin precursors and of ubiquitinated proteins. This enzyme is a thiol protease that recognizes and hydrolyzes a peptide bond at the C-terminal glycine of ubiquitin. Also binds to free monoubiquitin and may prevent its degradation in lysosomes. The homodimer may have ATP-independent ubiquitin ligase activity By similarity.

Catalytic activity

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).

Subunit structure

Monomer. Homodimer. Interacts with COPS5 and SNCA By similarity.

Subcellular location

Cytoplasm By similarity. Endoplasmic reticulum membrane; Lipid-anchor By similarity.

Post-translational modification

O-glycosylated By similarity.

Miscellaneous

In contrast to UCHL3, does not hydrolyze a peptide bond at the C-terminal glycine of NEDD8 By similarity.

Sequence similarities

Belongs to the peptidase C12 family.
