CC   -!- FUNCTION: Ubiquitin-protein hydrolase is involved both in the
CC       processing of ubiquitin precursors and of ubiquitinated proteins. This
CC       enzyme is a thiol protease that recognizes and hydrolyzes a peptide
CC       bond at the C-terminal glycine of ubiquitin.
CC       {ECO:0000269|PubMed:15533439}.
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;
CC   -!- SUBUNIT: Component of the 26S proteasome. Interacts with rpn10.
CC       {ECO:0000269|PubMed:15533439}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:10872838,
CC       ECO:0000269|PubMed:15533439}.
CC   -!- SIMILARITY: Belongs to the peptidase C12 family. {ECO:0000305}.
