By screening a custom library of small hairpin RNAs (shRNAs) targeting known chromatin regulators in a genetically defined AML mouse model, they identified the protein BRD4 as being required for disease maintenance. Suppression of BRD4 using shRNAs or the small-molecule inhibitor JQ1 led to robust antileukemic effects in vitro and in vivo, accompanied by terminal myeloid differentiation and elimination of leukemia stem cells. Similar sensitivities were observed in a variety of human AML cell lines and primary patient samples, revealing that JQ1 has broad activity in diverse AML subtypes. The effects of BRD4 suppression are, at least in part, due to its role in sustaining MYC (<a href="/entry/190080">190080</a>) expression to promote aberrant self-renewal, which implicates JQ1 as a pharmacologic means to suppress MYC in cancer. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=21814200" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p><p><a href="#3" class="mim-tip-reference" title="Dawson, M.

Examination of late-gestation mutant embryos revealed that loss of Brd4 in neural crest resulted in cohesinopathy-like phenotypes, including craniofacial, skeletal, and cardiac defects. These phenotypes were similar to those observed in mice with deletion of Nipbl. Immunoprecipitation analysis showed that BRD4 interacted with NIPBL in mouse and human cells. Mutation analysis revealed critical residues within a hydrophobic cleft of the extraterminal domain of human BRD4 that mediated NIPBL interaction. By interacting with NIPBL, BRD4 stabilized NIPBL binding on chromatin and regulated genome folding by maintaining normal genome folding architecture. Loss of Brd4 resulted in genomic architectural changes, but transcriptional dynamics in Brd4-depleted cells suggested that local transcriptional changes across the genome were unlikely to drive these architectural changes, indicating that the role of Brd4 in genome folding is distinct from its role in promoting transcription. Further analysis demonstrated that Brd4 regulated genome folding through Nipbl binding, and Brd4-Nipbl interaction promoted neural crest differentiation into smooth muscle. Moreover, smooth muscle differentiation defects resulting from loss of Brd4 were rescued by depletion of Wapl (<a href="/entry/610754">610754</a>), a negative regulator of cohesin complex, linking BRD4 function with regulation of cohesin. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=34611363" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p>

<span class="mim-text-font">
<p>Dey et al. (2000) cloned mouse Brd4, which they called Mcap. The deduced 1,400-amino acid protein has a calculated molecular mass of 155 kD. It contains 2 N-terminal bromodomains, a central ET domain, and several kinase-like motifs in its N-terminal half. By database analysis, Dey et al. (2000) identified a human cDNA encoding a 731-amino acid protein with the same domain organization as the N-terminal half of mouse Brd4, but lacking the C-terminal half. Northern blot analysis detected a transcript of about 6.5 kb in all adult and embryonic mouse tissues examined and in human cells. Western blot analysis of in vitro translated mouse Brd4 and HeLa cell lysates detected BRD4 at about 200 kD, suggesting posttranslational modification. Indirect immunofluorescent staining of HeLa cells and 2 mouse cell lines detected BRD4 in the nucleus. During interphase, BRD4 was uniformly distributed as fine grains in the nucleus, but it was excluded from nucleoli. In mitotic cells, BRD4 localized almost exclusively on condensed chromosomes. </p><p>French et al. (2001) described 2 alternatively spliced variants of BRD4 that encode proteins identical through their N-terminal halves, which include 2 bromodomains, the ET domain, and a serine-rich region. The longer variant has a C-terminal extension that includes a proline-rich region and a glutamine-rich region. </p><p>By EST database analysis and PCR of a human cDNA library, You et al. (2004) obtained a full-length cDNA encoding BRD4. The BRD4 protein contains 1,362 amino acids. </p><p>By Northern blot analysis, French et al. (2003) determined that BRD4 is ubiquitously expressed as 4.4- and 6.0-kb transcripts, which likely encode the short and long BRD4 isoforms. </p>

<strong>Gene Function</strong>

</div>
<span class="mim-text-font">
<p>By analyzing well-spread metaphase preparations of murine myeloid precursor cells, Dey et al. (2000) found Brd4 staining along the entire length of chromosomes, with the exception of centromeres. Brd4 chromosome association became visible following initiation of histone H3 (see 602810) phosphorylation and early chromosomal condensation and persisted until the end of mitosis. Differential salt extraction and FRAP analysis indicated that Brd4 was loosely associated with chromatin during interphase as well as mitosis. Supporting a role for BRD4 in G2/M transition, microinjection of anti-BRD4 antibody into HeLa cell nuclei completely inhibited entry into mitosis without abrogating ongoing DNA replication. Dey et al. (2000) concluded that BRD4 plays a role in chromosomal dynamics during mitosis. </p><p>Maruyama et al. (2002) found that ectopic expression of mouse Brd4 in mouse fibroblasts and HeLa cells inhibited cell cycle progression from G1 to S. Endogenous and transfected Brd4 interacted with replication factor C (RFC), the conserved 5-subunit complex essential for DNA replication, with Brd4 binding directly to the largest subunit, RFC1 (102579). In agreement with the inhibitory activity observed in vivo, recombinant Brd4 inhibited RFC-dependent DNA elongation reactions in vitro. Analysis of Brd4 deletion mutants indicated that both the interaction with human RFC1 and the inhibition of entry into S phase were dependent on the second bromodomain of Brd4. Cotransfection with RFC1 reduced the growth-inhibitory effect of Brd4. </p><p>You et al. (2004) identified BRD4 as a major cellular interacting partner of the bovine papillomavirus (BPV) E2 protein. They found that BRD4 associated with mitotic chromosomes and colocalized with E2 on mitotic chromosomes. The site of E2 binding mapped to the C-terminal domain of BRD4. Expression of this C-terminal BRD4 domain functioned in a dominant-negative manner to abrogate the colocalization of E2 with BRD4 on mitotic chromosomes, to block association of the viral episomes with BRD4, and to inhibit BPV-1 DNA-mediated cellular transformation. BRD4 also associated with human papillomavirus-16 E2, indicating that BRD4 binding may be a shared property of all papillomavirus E2 proteins. You et al. (2004) concluded that the interaction of E2 with BRD4 is required to ensure the tethering of viral genomes to the host mitotic chromosomes for persistence of viral episomes in papillomavirus-infected cells. </p><p>Jang et al. (2005) found that epitope-tagged mouse Brd4 interacted with cyclin T1 (143055) and CDK9 (603251) in core positive transcription elongation factor b (P-TEFb) complexes contained in HeLa cell nuclear extracts. The bromodomain of Brd4 was required for the interaction. Brd4 overexpression increased P-TEFb-dependent phosphorylation of the C-terminal domain of RNA polymerase II (see POLR2A; 180660) and stimulated transcription of a reporter plasmid driven by an HIV-1 promoter. Conversely, reduced Brd4 expression in mouse fibroblasts by small interfering RNA reduced RNA polymerase II C-terminal domain phosphorylation and transcription. Chromatin immunoprecipitation assays indicated that recruitment of P-TEFb to a promoter was dependent on Brd4, and recruitment was enhanced by increased chromatin acetylation. </p><p>About half of cellular P-TEFb exists in an inactive complex with 7SK snRNA (606515) and the HEXIM1 protein (607328). Yang et al. (2005) demonstrated that the remaining half associated with BRD4. In stress-induced HeLa cells, 7SK/HEXIM1-bound P-TEFb was converted into the BRD4-associated form. The association of P-TEFb with BRD4 was necessary to form the transcriptionally active P-TEFb, to recruit P-TEFb to a promoter, and to enable P-TEFb to contact the Mediator complex (see 602984). </p><p>Crawford et al. (2008) showed that activation of Brd4 in mice repressed tumor growth and metastasis and that BRD4 activation in human breast carcinomas induced a gene expression profile predictive of breast cancer outcome. </p><p>Zuber et al. (2011) described a nonbiased approach to probe epigenetic vulnerabilities in acute myeloid leukemia (AML; 601626), an aggressive hematopoietic malignancy that is often associated with aberrant chromatin states. By screening a custom library of small hairpin RNAs (shRNAs) targeting known chromatin regulators in a genetically defined AML mouse model, they identified the protein BRD4 as being required for disease maintenance. Suppression of BRD4 using shRNAs or the small-molecule inhibitor JQ1 led to robust antileukemic effects in vitro and in vivo, accompanied by terminal myeloid differentiation and elimination of leukemia stem cells. Similar sensitivities were observed in a variety of human AML cell lines and primary patient samples, revealing that JQ1 has broad activity in diverse AML subtypes. The effects of BRD4 suppression are, at least in part, due to its role in sustaining MYC (190080) expression to promote aberrant self-renewal, which implicates JQ1 as a pharmacologic means to suppress MYC in cancer. </p><p>Dawson et al. (2011) demonstrated that I-BET151, a novel small molecule inhibitor of the BET family, of which BRD4 is a member, has profound efficacy against human and murine MLL-fusion leukemia cell lines, through the induction of early cell cycle arrest and apoptosis. I-BET151 treatment in 2 human leukemia cell lines with different MLL fusions altered the expression of a common set of genes whose function may account for these phenotypic changes. The mode of action of I-BET151 is, at least in part, due to the inhibition of transcription at key genes BCL2 (151430), C-MYC, and CDK6 (603368) through the displacement of BRD3/4, PAFc, and SEC components from chromatin. In vivo studies indicated that I-BET151 has significant therapeutic value, providing survival benefit in 2 distinct mouse models of murine MLL-AF9 and human MLL-AF4 leukemia. </p><p>Using a genomewide small interfering RNA screen and secondary screens, Smith et al. (2010) identified 96 cellular genes that contributed to viral E2 protein-mediated repression of the human papillomavirus (HPV) long control region, which controls viral oncogene expression. In addition to the E2-binding protein BRD4, other genes implicated included the demethylase SMCX (KDM5C; 314690) and EP400 (606265), a component of the NUA4/TIP60 histone acetyltransferase complex (see 601409). Smith et al. (2010) concluded that HPV E2 uses multiple cellular proteins to inhibit expression of its oncogenes. </p><p>Floyd et al. (2013) investigated the role of chromatin structure in the DNA damage response by monitoring ionizing radiation-induced signaling and response events with a high-content multiplex RNA-mediated interference screen of chromatin-modifying and -interacting genes. Floyd et al. (2013) found that isoform B of BRD4, in which the C-terminal domain containing the P-TEFb-interacting region is replaced with a divergent 75-amino acid segment, functions as an endogenous inhibitor of DNA damage response signaling by recruiting the condensin II chromatin remodeling complex to acetylated histones through bromodomain interactions. Loss of this isoform resulted in relaxed chromatin structure, rapid cell cycle checkpoint recovery, and enhanced survival after irradiation, whereas functional gain of this isoform compacted chromatin, attenuated DNA damage response signaling, and enhanced radiation-induced lethality. Floyd et al. (2013) concluded that their data implicated BRD4 as an insulator of chromatin that can modulate the signaling response to DNA damage. </p><p>Muhar et al. (2018) combined SLAM-seq (thiol(SH)-linked alkylation for the metabolic sequencing of RNA), a method for direct quantification of newly synthesized mRNAs, with pharmacologic and chemical-genetic perturbation in order to define regulatory functions of 2 transcriptional hubs in cancer, BRD4 and MYC (190080), and to interrogate direct responses to BET bromodomain inhibitors (BETis). Muhar et al. (2018) found that BRD4 acts as general coactivator of RNA POL2 (see 180660)-dependent transcription, which is broadly repressed upon high-dose BETi treatment. At doses triggering selective effects in leukemia, BETis deregulate a small set of hypersensitive targets, including MYC. In contrast to BRD4, MYC primarily acts as a selective transcriptional activator controlling metabolic processes such as ribosome biogenesis and de novo purine synthesis. Muhar et al. (2018) concluded that their study established a simple and scalable strategy to identify direct transcriptional targets of any gene or pathway. </p><p>Choe et al. (2018) demonstrated that METTL3 (612472) enhances translation only when tethered to reporter mRNA at sites close to the stop codon, supporting a mechanism of mRNA looping for ribosome recycling and translational control. Electron microscopy revealed the topology of individual polyribosomes with single METTL3 foci in close proximity to 5-prime cap-binding proteins. Choe et al. (2018) identified a direct physical and functional interaction between METTL3 and the eukaryotic translation initiation factor 3 subunit H (EIF3H; 603912). METTL3 promotes translation of a large subset of oncogenic mRNAs, including BRD4, that is also N6-methyladenosine (m6A)-modified in human primary lung tumors. The METTL3-EIF3H interaction is required for enhanced translation, formation of densely packed polyribosomes, and oncogenic transformation. METTL3 depletion inhibits tumorigenicity and sensitizes lung cancer cells to BRD4 inhibition. Choe et al. (2018) concluded that these findings uncovered a mechanism of translation control that is based on mRNA looping. </p><p>Using a genetic screen, Sdelci et al. (2019) identified human MTHFD1 (172460) as a functional partner of BRD4. BRD4 physically interacted with MTHFD1 in nucleus and recruited it to chromatin. The interaction was enhanced by binding of the BRD4 bromodomains to acetylated lysines on the surface of MTHFD1. Chromatin immunoprecipitation-sequencing analysis revealed that MTHFD1 regulated gene expression by colocalizing with BRD4 at promoter and enhancer regions, where H3K27ac was also enriched. Furthermore, BRD4 boosted the C1-tetrahydrofolate synthase activity of MTHFD1, and loss of either MTHFD1 or BRD4 resulted in similar changes in nuclear metabolite composition and gene expression, correlating BRD4-dependent epigenetic regulation and folate metabolism. Antifolates synergized with BRD4 inhibitors and impaired cancer cell proliferation without exerting general toxicity. </p><p>By ChIP-seq analysis in mouse embryonic stem cells (mESCs), Olley et al. (2021) showed that a Brd4 Y430C mutation reduced occupancy of Brd4 protein at cis-regulatory elements (CREs). However, the decreased occupancy of the Brd4 Y430C mutant at CREs was not sufficient to affect the transcription of associated genes in mESCs, despite the role of Brd4 in transcriptional regulation. Instead, the Brd4 Y430C mutant resulted in a delayed cell cycle, increased cell cycle checkpoint activation, increased DNA damage response (DDR) signaling, and defective double-strand break (DSB) in mESCs. The DDR defect observed in mESCs with the Brd4 Y430C mutation was also seen in lymphoblastoid cell lines with a Cornelia de Lange syndrome (CDLS; 122470)-associated NIPBL (608667) mutation, suggesting that increased DDR signaling and/or impaired DNA repair pathway choice balance might contribute to the etiology of CDLS. </p>

<p>Faivre et al. (2020) performed a medicinal chemistry campaign that led to the discovery of ABBV-744, a highly potent and selective inhibitor of the BD2 domain of BET family proteins with drug-like properties. In contrast to the broad range of cell growth inhibition induced by dual-bromodomain BET inhibitors, the antiproliferative activity of ABBV-744 was largely, but not exclusively, restricted to cell lines of acute myeloid leukemia (601626) and prostate cancer (176807) that expressed the full-length androgen receptor (AR; 313700). ABBV-744 retained robust activity in prostate cancer xenografts, and showed fewer platelet and gastrointestinal toxicities than the dual-bromodomain BET inhibitors. Analyses of RNA expression and chromatin immunoprecipitation followed by sequencing revealed that ABBV-744 displaced BRD4 from AR-containing superenhancers and inhibited AR-dependent transcription, with less impact on global transcription compared with a dual-bromodomain BET inhibitor. </p>

<p>The balanced translocation t(15;19) has been identified in midline carcinomas adjacent to the respiratory tract in children and young adults and is associated with poor survival and a treatment-refractory course. French et al. (2001) mapped the translocation breakpoints in 2 patients with t(15;19)(q13;p13.1) carcinomas. The chromosome 19 translocation breakpoints were between introns 10 and 13 in the 3-prime end of the BRD4 coding sequence in both cancers. The breakpoints split the coding sequence of the longer BRD4 transcript and left the short transcript unaltered. The breakpoints in chromosome 15q13 localized to an approximately 9-kb region containing the NOP10 gene (NOLA3; 606471) gene. FISH screening of 13 supradiaphragmatic pediatric carcinomas revealed a sinonasal carcinoma with a chromosome 19p13.1 and 15q13 rearrangement. The other 12 carcinomas lacked chromosome 15 or 19 rearrangements. </p><p>French et al. (2003) determined that the BRD4 fusion partner in the t(15;19) translocation is NUT (608963). Sequence analysis indicated that the translocations in 2 affected tumors were identical and resulted in the in-frame fusion of exon 10 of BRD4 with exon 2 of NUT. The oncogenic fusion protein contains the N-terminal BRD4 sequence up to the serine-rich region, followed by almost the entire NUT sequence. It lacks only the first 5 NUT residues. Northern blot analysis detected a 6.4-kb fusion transcript in a t(15;19)-positive carcinoma cell line. No NUT/BRD4 transcripts were detected. </p>

<p>Among 92 patients with features of Cornelia de Lange syndrome who were negative for mutations in known causative genes, Olley et al. (2018) identified 2 unrelated patients with de novo heterozygous mutations in the BRD4 gene (see CDLS6, 620568): a missense mutation (Y430C; 608749.0001) and a 1.04 Mb deletion that included BRD4 and 28 other protein-coding genes. Two additional patients who were not part of the original cohort were identified with de novo heterozygous frameshift mutations in BRD4 (see, e.g., 608749.0002). The authors then reviewed phenotypes of other patients with heterozygous multigenic deletions encompassing BRD4 and recognized a significant overlap with the CDLS phenotype, suggesting that BRD4 haploinsufficiency is the likely cause of CDLS6. The authors showed that the BRD4 missense variant (Y430C) resulted in more typical CDLS; this variant retained the ability to coimmunoprecipitate with NIPBL (608667), the causative gene in CDLS1 (122470), but had decreased binding to acetylated histones of promoter and superenhancer genes. Functional analyses demonstrated that BRD4 and NIPBL coregulated binding at superenhancer genes and appeared to coregulate developmental gene expression. </p><p>Through an international collaboration, Jouret et al. (2022) identified 2 fetuses and 12 patients aged 10 weeks to 32 years with mutations involving the BRD4 gene. The mutations included 8 point mutations and 6 large deletions. Of the 8 point mutations, 4 were premature truncating mutations (see, e.g., 608749.0003) and 4 were missense variants (see, e.g., 608749.0001, 608749.0004); one mutation (Y430C; 608759.0001) had previously been reported. Deletion size varied from 46 kb to 2.2 Mb; the 46-kb deletion overlapped only the BRD4 gene. Whereas some of the patients had microcephaly, arched eyebrows, synophrys, short nose, and anteverted nostrils, the authors did not think that any of the 14 patients had a classic CDLS phenotype because none had the typical features of growth failure, hypertrichosis, or radial/limb anomalies. </p>

<span class="mim-text-font">
<p>Linares-Saldana et al. (2021) found that mice with neural crest-specific deletion of Brd4 underwent prenatal lethality. Examination of late-gestation mutant embryos revealed that loss of Brd4 in neural crest resulted in cohesinopathy-like phenotypes, including craniofacial, skeletal, and cardiac defects. These phenotypes were similar to those observed in mice with deletion of Nipbl. Immunoprecipitation analysis showed that BRD4 interacted with NIPBL in mouse and human cells. Mutation analysis revealed critical residues within a hydrophobic cleft of the extraterminal domain of human BRD4 that mediated NIPBL interaction. By interacting with NIPBL, BRD4 stabilized NIPBL binding on chromatin and regulated genome folding by maintaining normal genome folding architecture. Loss of Brd4 resulted in genomic architectural changes, but transcriptional dynamics in Brd4-depleted cells suggested that local transcriptional changes across the genome were unlikely to drive these architectural changes, indicating that the role of Brd4 in genome folding is distinct from its role in promoting transcription. Further analysis demonstrated that Brd4 regulated genome folding through Nipbl binding, and Brd4-Nipbl interaction promoted neural crest differentiation into smooth muscle. Moreover, smooth muscle differentiation defects resulting from loss of Brd4 were rescued by depletion of Wapl (610754), a negative regulator of cohesin complex, linking BRD4 function with regulation of cohesin. </p>

To ensure long-term funding for the OMIM project, we have diversified
our revenue stream. We are determined to keep this website freely
accessible. Unfortunately, it is not free to produce. Expert curators
review the literature and organize it to facilitate your work. Over 90%
of the OMIM's operating expenses go to salary support for MD and PhD
science writers and biocurators. Please join your colleagues by making a
donation now and again in the future. Donations are an important
component of our efforts to ensure long-term funding to provide you the
information that you need at your fingertips.
