CC -!- FUNCTION: Ubiquitin-protein hydrolase involved both in the processing
CC of ubiquitin precursors and of ubiquitinated proteins. This enzyme is a
CC thiol protease that recognizes and hydrolyzes a peptide bond at the C-
CC terminal glycine of ubiquitin (By similarity). Also binds to free
CC monoubiquitin and may prevent its degradation in lysosomes (By
CC similarity). The homodimer may have ATP-independent ubiquitin ligase
CC activity (By similarity). {ECO:0000250|UniProtKB:P09936,
CC ECO:0000250|UniProtKB:Q9R0P9}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Thiol-dependent hydrolysis of ester, thioester, amide, peptide
CC and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76-
CC residue protein attached to proteins as an intracellular targeting
CC signal).; EC=3.4.19.12; Evidence={ECO:0000250|UniProtKB:P09936};
CC -!- SUBUNIT: Monomer. Homodimer. Interacts with COPS5 and SNCA (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Endoplasmic reticulum
CC membrane {ECO:0000250}; Lipid-anchor {ECO:0000250}. Nucleus
CC {ECO:0000250}. Note=Found both cytoplasmic and nuclear in
CC cytotrophoblasts and decidual cells. {ECO:0000269|PubMed:15664418}.
CC -!- TISSUE SPECIFICITY: Expressed in the placenta at all stages of
CC pregnancy. Expression increases as pregnancy progresses.
CC {ECO:0000269|PubMed:15664418}.
CC -!- PTM: O-glycosylated. {ECO:0000250}.
CC -!- MISCELLANEOUS: In contrast to UCHL3, does not hydrolyze a peptide bond
CC at the C-terminal glycine of NEDD8. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the peptidase C12 family. {ECO:0000305}.
CC -!- CAUTION: The homodimer may have ATP-independent ubiquitin ligase
CC activity. However, in another study, UCHL1 was shown to lack ubiquitin
CC ligase activity. {ECO:0000250|UniProtKB:P09936}.
