BAP1 (Ubiquitin carboxyl-terminal hydrolase BAP1) is an enzyme. The public catalogues list it as a drug target, an oncogene driver, a tumour suppressor and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Renal cell carcinoma, Mesothelioma, Biliary tract cancer and 5 more. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

Deubiquitinating enzyme that plays a key role in chromatin by mediating deubiquitination of histone H2A and HCFC1. Catalytic component of the polycomb repressive deubiquitinase (PR-DUB) complex, a complex that specifically mediates deubiquitination of histone H2A monoubiquitinated at 'Lys-120' (H2AK119ub1). Does not deubiquitinate monoubiquitinated histone H2B. The PR-DUB complex is an epigenetic regulator of gene expression and acts as a transcriptional coactivator, affecting genes involved in development, cell communication, signalling, cell proliferation and cell viability. Antagonises PRC1 mediated H2AK119ub1 monoubiquitination. As part of the PR-DUB complex, associates with chromatin enriched in histone marks H3K4me1, H3K4me3, and H3K27Ac, but not in H3K27me3. Location: Cytoplasm; Nucleus; Chromosome (UniProt). Locus 3p21.1 (HGNC).
