Functioni

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. 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.2 Publications

Post-translational modificationi

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 (By similarity).By similarity

Domaini

The 2 bromo domains mediate specific binding to acetylated histones via Asn-140 and Asn-434, respectively (PubMed:19828451). 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 (By similarity).By similarity1 Publication
The NET domain mediates interaction with a number of chromatin proteins involved in transcription regulation (WHSC1L1, JMJD6, CHD4, GLTSCR1 and ATAD5).By similarity
The C-terminal (CTD) region mediates interaction and recruitment of CDK9 and CCNT1 subunits of the P-TEFb complex. It is also required for maintenance of higher-order chromatin structure (By similarity).By similarity

Miscellaneous

Some specific inhibitors of Brd4 that prevent binding to acetylated histones by binding Asn-140 and Asn-434 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. 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:21814200, PubMed:21964340).2 Publications

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
