"As a deubiquitinating enzyme, BAP1 contributes to gene transcription, cell differentiation, DNA damage repair, apoptosis, and cell metabolism in tumor inhibition."

reach
"In addition, melanoma specific network analysis followed by Kaplan-Meier analysis along with log-rank tests identified tyrosinase, hedgehog acyltransferase, BRCA1 associated protein 1 and melanocyte inducing transcription factor as potential therapeutic targets for melanoma."

reach
"These included the SETD1A, KMT2C and MLL3, KMT2E and MLL5, and KMT2A and MLL1 methyltransferases that install activating histone H3-lysine 4 trimethylation (H3K4me3) marks; OGT (O-GlcNac transferase), a protein that modulates multiple cell pathways but more recently has been implicated in promoting promoter occupancy of RNAPII; and BAP1 (BRCA1 Associated Protein 1), a deubiquitinase that stimulates transcription, at least in part, by removing repressive histone H2A-K119 monoubiquitin."

reach
"These data indicate that BaP1 triggers transcription mechanisms in FLSs that result in an increase in COX-2 protein content."

reach
"The observation that BaP1 induced translocation of the NF-κB p50 and RelA (p65) subunits into the nucleus gives further support to the hypothesis that this transcription factor is activated by BaP1 and provides a mechanism for this activation."

reach
"p53 binds to the SLC7A11 promoter, directly suppressing its transcription; the nuclear deubiquitinase (DUB) BAP1 represses SLC7A11 transcription by removing histone 2A ubiquitination from the SLC7A11 promoter; and KEAP1 represses SLC7A11 transcription through degrading NRF2, a master transcription factor of antioxidant response and regulator of SLC7A11."

eidos
"Taken together , these results establish that PRC1 is epistatic to BAP1.com and that BAP1 promotes transcription by counteracting PRC1-mediated H2A ubiquitination ( Fig. 7 ) ."

reach
"Previously, we found that hypoxia-inducible factor 2α (HIF2α) and BAP1 activate interferon-stimulated gene factor 3 (ISGF3), a transcription factor activated by type I interferons and a tumor suppressor in ccRCC xenograft models."

reach
"BAP1 activates transcription in an enzymatic-activity-dependent manner and regulates the expression of a variety of genes involved in numerous cellular processes."

reach
"RNA sequencing and chromatin immunoprecipitation coupled with quantitative PCR analyses revealed that reduced BAP1 expression suppressed upregulation of the transcription factors AP-1 and EGR1/2, as well as myeloid dysplasia associated genes, by retarding H2AK119Ub removal caused by ASXL1 mutation."

reach
"BAP1 complex promotes transcription by opposing PRC1 mediated H2A ubiquitylation."
