Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Activity: Ubiquitinyl hydrolase 1, with EC number 3.4.19.12 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [CALYP_DROME] 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. [ASX_DROME] Atypical Polycomb group protein, which may be involved in both Polycomb group (PcG) and trithorax group (trxG) complexes. Non-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. PcG and trxG proteins act by forming multiprotein complexes, which are respectively required to maintain the transcriptionally repressive and transcriptionally active state of homeotic genes throughout development. PcG and trxG protein complexes are not required to initiate repression and activation, but to maintain it during later stages of development.
