General annotation (Comments)

Function

Polycomb group (PcG) protein. Catalytic component of the PR-DUB complex, a complex that specifically mediates deubiquitination of histone H2A monoubiquitinated at 'Lys-118' (H2AK118ub1). Does not deubiquitinate monoubiquitinated histone H2B. Required to maintain the transcriptionally repressive state of homeotic genes throughout development. The PR-DUB complex has weak or no activity toward 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains 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

Component of the PR-DUB complex, at least composed of calypso and Asx By similarity.

Subcellular location

Nucleus By similarity. Note: Localizes to PcG response elements (PREs) By similarity.

Sequence similarities

Belongs to the peptidase C12 family. BAP1 subfamily.
