Entrez Gene Summary for BRD4 Gene

  • The protein encoded by this gene is homologous to the murine protein MCAP, which associates with chromosomes during mitosis, and to the human RING3 protein, a serine/threonine kinase. Each of these proteins contains two bromodomains, a conserved sequence motif which may be involved in chromatin targeting. This gene has been implicated as the chromosome 19 target of translocation t(15;19)(q13;p13.1), which defines an upper respiratory tract carcinoma in young people. Two alternatively spliced transcript variants have been described. [provided by RefSeq, Jul 2008]

GeneCards Summary for BRD4 Gene

BRD4 (Bromodomain Containing 4) is a Protein Coding gene. Among its related pathways are Chromatin Regulation / Acetylation and Beta-Adrenergic Signaling. GO annotations related to this gene include chromatin binding and lysine-acetylated histone binding. An important paralog of this gene is BRDT.

UniProtKB/Swiss-Prot for BRD4 Gene

  • Chromatin reader protein that recognizes and binds acetylated histones and plays a key role in transmission of epigenetic memory across cell divisions and transcription regulation. Remains associated with acetylated chromatin throughout the entire cell cycle and provides epigenetic memory for postmitotic G1 gene transcription by preserving acetylated chromatin status and maintaining high-order chromatin structure. During interphase, plays a key role in regulating the transcription of signal-inducible genes by associating with the P-TEFb complex and recruiting it to promoters: BRD4 is required to form the transcriptionally active P-TEFb complex by displacing negative regulators such as HEXIM1 and 7SKsnRNA complex from P-TEFb, thereby transforming it into an active form that can then phosphorylate the C-terminal domain (CTD) of RNA polymerase II. Promotes phosphorylation of Ser-2 of the C-terminal domain (CTD) of RNA polymerase II. According to a report, directly acts as an atypical protein kinase and mediates phosphorylation of Ser-2 of the C-terminal domain (CTD) of RNA polymerase II; these data however need additional evidences in vivo (PubMed:22509028). In addition to acetylated histones, also recognizes and binds acetylated RELA, leading to further recruitment of the P-TEFb complex and subsequent activation of NF-kappa-B. Also acts as a regulator of p53/TP53-mediated transcription: following phosphorylation by CK2, recruited to p53/TP53 specific target promoters.

  • Isoform B: Acts as a chromatin insulator in the DNA damage response pathway. Inhibits DNA damage response signaling by recruiting the condensin-2 complex to acetylated histones, leading to chromatin structure remodeling, insulating the region from DNA damage response by limiting spreading of histone H2AFX/H2A.x phosphorylation

Tocris Summary for BRD4 Gene

  • Bromodomains (BRDs) are epigenetic readers that selectively recognize acetylated lysine (Kac) residues on histone protein tails, and are the only known protein modules that target Kac residues. There are approximately 62 unique human bromodomains, most of which can be classified according to sequence identity into nine groups.

    Quaternary structure:
    • Interacts with p53/TP53; the interaction is direct. Interacts (via CTD region) with CDK9 and CCNT1, acting as an associated component of P-TEFb complex. Interacts with RELA (when acetylated at Lys-310). Interacts (via NET domain) with WHSC1L1, JMJD6, CHD4, GLTSCR1 and ATAD5. Isoform B: interacts with NCAPD3 and SMC2. Interacts with bovine papillomavirus type 1 regulatory protein E2 and human herpes virus-8 (HHV-8) protein LANA. These interactions may serve for the tethering of viral genomes to host mitotic chromosomes allowing successful partitioning of the viral genome during cell division. Interacts with Epstein-Barr virus (EBV) protein EBNA1; this interaction facilitates transcriptional activation by EBNA1.
    Miscellaneous:
    • Some specific inhibitors of BRD4 that prevent binding to acetylated histones by binding Asn-140 and Asn-433 are promising therapeutic molecules for the treatment of leukemias. JQ1, a thieno-triazolo-1,4-diazepine derivative, and I-BET, a benzodiazepine derivative, have been tested on tumors with success (PubMed:20871596, PubMed:21068722, PubMed:21964340). Treatment with GSK1210151A (I-BET151, a I-BET derivative) has strong effets on mixed lineage leukemia and promotes myeloid differentiation and leukemia stem-cell depletion (PubMed:21964340).

Post-translational modifications for BRD4 Gene

  • Phosphorylation by CK2 disrupt the intramolecular binding between the bromo domain 2 and the NPS region and promotes binding between the NPS and the BID regions, leading to activate the protein and promote binding to acetylated histones. In absence of phosphorylation, BRD4 does not localize to p53/TP53 target gene promoters, phosphorylation promoting recruitment to p53/TP53 target promoters.

  • The C-terminal (CTD) region mediates interaction and recruitment of CDK9 and CCNT1 subunits of the P-TEFb complex (PubMed:16109376, PubMed:16109377). It is also required for maintenance of higher-order chromatin structure (PubMed:22334664).:
    • O60885
  • The 2 bromo domains mediate specific binding to acetylated histones via Asn-140 and Asn-433, respectively (PubMed:20871596). The exact combination of modified histone tails required to recruit BRD4 to target genes is still unclear. The first bromo domain has high affinity for acetylated histone H4 tail, whereas the second bromo domain recognizes multiply acetylated marks in histone H3 (PubMed:22464331). A number of specific inhibitors bind competitively to acetyl-lysine-binding residues Asn-140 and Asn-433, promoting removal from acetylated histones. Many of these inhibitors are benzodiazepine derivatives (PubMed:22137933, PubMed:22136404, PubMed:23517011, PubMed:23530754).:
