Function Deubiquitinating enzyme that plays a key role in chromatin by mediating deubiquitination of histone H2A and HCFC1 (PubMed:12485996, PubMed:18757409, PubMed:20436459, PubMed:25451922, PubMed:35051358). Catalytic component of the polycomb repressive deubiquitinase (PR-DUB) complex, a complex that specifically mediates deubiquitination of histone H2A monoubiquitinated at 'Lys-120' (H2AK119ub1) (PubMed:20436459, PubMed:25451922, PubMed:30664650, PubMed:35051358). Does not deubiquitinate monoubiquitinated histone H2B (PubMed:20436459, PubMed:30664650). The PR-DUB complex is an epigenetic regulator of gene expression and acts as a transcriptional coactivator, affecting genes involved in development, cell communication, signaling, cell proliferation and cell viability (PubMed:20805357, PubMed:30664650, PubMed:36180891). Antagonizes PRC1 mediated H2AK119ub1 monoubiquitination (PubMed:30664650). As part of the PR-DUB complex, associates with chromatin enriched in histone marks H3K4me1, H3K4me3, and H3K27Ac, but not in H3K27me3 (PubMed:36180891). Recruited to specific gene-regulatory regions by YY1 (PubMed:20805357). Acts as a regulator of cell growth by mediating deubiquitination of HCFC1 N-terminal and C-terminal chains, with some specificity toward 'Lys-48'-linked polyubiquitin chains compared to 'Lys-63'-linked polyubiquitin chains (PubMed:19188440, PubMed:19815555). Deubiquitination of HCFC1 does not lead to increase stability of HCFC1 (PubMed:19188440, PubMed:19815555). Interferes with the BRCA1 and BARD1 heterodimer activity by inhibiting their ability to mediate ubiquitination and autoubiquitination (PubMed:19117993). It however does not mediate deubiquitination of BRCA1 and BARD1 (PubMed:19117993). Able to mediate autodeubiquitination via intramolecular interactions to counteract monoubiquitination at the nuclear localization signal (NLS), thereby protecting it from cytoplasmic sequestration (PubMed:24703950). Negatively regulates epithelial-mesenchymal transition (EMT) of trophoblast stem cells during placental development by regulating genes involved in epithelial cell integrity, cell adhesion and cytoskeletal organization (PubMed:34170818).
Catalytic activity CATALYTIC ACTIVITY: Reaction=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).; EC=3.4.19.12; Evidence=;
Subellular location Cytoplasm . Nucleus . Chromosome . Note=Mainly nuclear (PubMed:24703950, PubMed:30664650). Binds to chromatin (PubMed:30664650). Localizes to the cytoplasm when monoubiquitinated by the E2/E3 hybrid ubiquitin-protein ligase UBE2O (PubMed:24703950). Recruitment to chromatin is dependent on ASXL1/2/3 and recruitment to specific genes on FOXK1/2 (By similarity). Nuclear localization is redundantly mediated by the importin and transportin systems; TNPO1/transportin-1 is the major mediator of nuclear localization (PubMed:35446349).
Tissues Highly expressed in testis, placenta and ovary (PubMed:9528852). Expressed in breast (PubMed:9528852). levels in the placenta increase over the course of pregnancy (PubMed:34170818).
Structure Core component of the polycomb repressive deubiquitinase (PR-DUB) complex, at least composed of BAP1, one of ASXL1, ASXL2 or (probably) ASXL3, and one of MBD5 or MBD6 (PubMed:20436459, PubMed:24634419, PubMed:30664650, PubMed:36180891). The PR-DUB core associates with a number of accessory proteins, including FOXK1, FOXK2, KDM1B, HCFC1, YY1 and OGT; KDM1B specifically associates with ASXL2 PR-DUB complexes (Probable) (PubMed:20805357, PubMed:30664650). The BAP1 deubiquitinase activity is not required for PR-DUB assembly (PubMed:20805357). Homodimerizes (via coiled-coil hinge-region between the UCH and UCH37-like C-terminal domains) to mediate assembly of 2 copies of the BAP1-ASXL heterodimer into a bisymmetric tetramer; dimerization enhances association with nucleosomes (PubMed:30258054, PubMed:35446349). The PR-DUB complex associates with nucleosomes to mediate deubiquitination of 'lys-120' of histone H2AK118ub1 substrates; the association requires the positively charged C-terminal tail of BAP1 (PubMed:30258054, PubMed:36991118, PubMed:37556531). Interacts (via UCH37-like C-terminal domain) with ASXL1 (via DEUBAD domain); the interaction is direct and forms a ubiquitin binding cleft (PubMed:36180891, PubMed:36991118, PubMed:37556531). The interaction with ASXL1 stabilzes BAP1 but is not required for nucleosome binding (PubMed:36180891). Associates (via C-terminus) with nucleosome and chromatosome complexes through direct interaction with DNA and the histone3/4 dimer; this association displaces the histone-2A C-terminal tail, extending and orienting the H2AK118ub1 substrate towards the BAP1 deubiquitinase active site (PubMed:36991118, PubMed:37556531). Also interacts (via arginine finger) directly with the histone H2A-H2B acidic patch; this interaction is not critical for nucleosome-chromatosome association but may play a role in orienting the H2AK118ub1 substrate towards the PR-DUB complex active site (PubMed:36991118). Interacts with BRCA1 (via the RING finger) (PubMed:19117993, PubMed:9528852). Interacts (via HBM-like motif) with HCFC1 (PubMed:19188440, PubMed:19815555, PubMed:20805357). Interacts (via UCH37-like C-terminal domain) with YY1; the interaction is direct and requires the interaction with HCFC1 (PubMed:20805357). Interacts (when phosphorylated at Thr-493) with FOXK1 (PubMed:25451922). Interacts (when phosphorylated at Thr-493) with FOXK2; leading to recruitment of the PR-DUB complex and repression of FOXK2 target genes (PubMed:24748658, PubMed:25451922). Interacts (via non-classical PY-NLS) with TNPO1/transportin-1 (via HEAT repeats 8-12); the interaction is direct, mediates BAP1 nuclear localization and disrupts BAP1 homodimerization (PubMed:35446349). Interacts (via C-terminus) with KPNA1/importin alpha5 and KPNA2/importin alpha1; these interactions can contribute to BAP1 nuclear localization but are less important than the interaction with TNPO1/transportin-1 (PubMed:35446349). The interaction with TNPO1/transportin-1 disrupts homodimerization and blocks ubiquitination by UBE2O (PubMed:35446349).
Post-translational modification PTM: Ubiquitinated: monoubiquitinated at multiple sites within its nuclear localization signal (NLS) BY UBE2O, leading to cytoplasmic retention (PubMed:24703950). Able to mediate autodeubiquitination via intramolecular interactions to counteract cytoplasmic retention (PubMed:24703950). Monoubiquitinated on at least 4 sites near or within its PY-NLS (PubMed:35446349).
