CC   -!- FUNCTION: Polycomb group (PcG) protein. Catalytic component of the PR-
CC       DUB complex, a complex that specifically mediates deubiquitination of
CC       histone H2A monoubiquitinated at 'Lys-118' (H2AK118ub1). Does not
CC       deubiquitinate monoubiquitinated histone H2B. Required to maintain the
CC       transcriptionally repressive state of homeotic genes throughout
CC       development. The PR-DUB complex has weak or no activity toward 'Lys-
CC       48'- and 'Lys-63'-linked polyubiquitin chains (By similarity).
CC       {ECO:0000250}.
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 PR-DUB complex, at least composed of calypso
CC       and Asx. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Note=Localizes to PcG
CC       response elements (PREs). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the peptidase C12 family. BAP1 subfamily.
CC       {ECO:0000305}.
