Supplementary information

The Brd4 protein also known as Bromodomain containing protein 4 plays an important role as a transcriptional regulator. It recognizes acetylated lysine residues on histone tails through its bromodomains. This binding impacts chromatin structure and transcriptional activation. The Brd4 protein has a molecular weight of around 150 kDa and is often used as a marker in studies using Brd4 western blot techniques. It mainly expresses in the nucleus of most cell types and is an important focus for developing Brd4 anticuerpos useful for detecting protein size discrepancies in research.

Biological function summary

Brd4 plays a significant role in regulating gene expression during cell cycle progression. It interacts with the Mediator complex enabling communication between transcriptional activators and RNA polymerase II. This protein is integral for maintaining chromatin in an active state ensuring accessibility for transcription machinery. Moreover Brd4 size and functionality relate to the elongation of transcription by RNA polymerase II ensuring the seamless expression of genes essential for cellular functions.

Pathways

Brd4 integrates into transcriptional and epigenetic regulation pathways. It acts in the positive regulation of the MYC pathway directly linking Brd4 with proto-oncogene c-Myc. Also Brd4 engages in the JAK/STAT signaling pathway where its activity affects cell growth and immune response. These interactions establish Brd4 as a central regulator within these pathways facilitating communication and coordination among molecular players.

Brd4 link heavily to cancer and inflammatory diseases. Aberrant Brd4 activity often associates with various cancers including leukemia where its regulation impacts oncogenic drivers. Clinically targeting Brd4 presents a therapeutic avenue as its inhibition affects cyclin-dependent kinase 9 (CDK9) an important regulator of the cell cycle. Similarly Brd4 alterations implicate in inflammatory disorders impacting nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) signaling revealing pathways for intervening in pathogenic processes.

Target data

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 (PubMed : 20871596, PubMed : 23086925, PubMed : 23317504, PubMed : 29176719, PubMed : 29379197). 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 (PubMed : 22334664, PubMed : 23317504, PubMed : 23589332). 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 (PubMed : 16109376, PubMed : 16109377, PubMed : 19596240, PubMed : 23589332, PubMed : 24360279). Also recruits P-TEFb complex to distal enhancers, so called anti-pause enhancers in collaboration with JMJD6 (PubMed : 16109376, PubMed : 16109377, PubMed : 19596240, PubMed : 23589332, PubMed : 24360279). BRD4 and JMJD6 are 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 (PubMed : 16109376, PubMed : 16109377, PubMed : 19596240, PubMed : 23589332, PubMed : 24360279). Regulates differentiation of naive CD4(+) T-cells into T-helper Th17 by promoting recruitment of P-TEFb to promoters (By similarity). Promotes phosphorylation of 'Ser-2' of the C-terminal domain (CTD) of RNA polymerase II (PubMed : 23086925). 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 (PubMed : 19103749). Also acts as a regulator of p53/TP53-mediated transcription : following phosphorylation by CK2, recruited to p53/TP53 specific target promoters (PubMed : 23317504).. 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 H2AX/H2A.x phosphorylation.
