WebKnockdown of Brd4 in human cells alleviates E2-mediated repression of HPV transcription. The E2-interacting domain at the extreme C terminus and the chromatin targeting activity of a bromodomain-containing region are both essential for the corepressor activity of Brd4. Interestingly, E2–Brd4 blocks the recruitment of TFIID and RNA polymerase ... WebMar 10, 2024 · Data suggest that Brd4 is essential for Toll-like receptor-stimulated interferon-beta (IFNB) gene transcription by permitting transcription factors to interact with the IFNB promoter in macrophages. Data show that hematopoietic transcription factors (TFs) promote bromodomain containing 4 protein (BRD4) recruitment to their …
BRD4 and MYC: power couple in transcription and disease
WebJul 22, 2024 · BRD4 is a bromodomain and extra terminal (BET) protein that has been described as a protein with many roles. It has been variously defined as a transcription cofactor, chromatin reader and regulator, recruiting and scaffolding factor, a DNA damage response factor and a mitotic bookmark. WebAug 7, 2024 · The BET family member BRD4 recruits positive transcription elongation factor b (P-TEFb) to promoters and enhancers, releasing RNA polymerase II and initiating transcriptional elongation . JQ1, a BET inhibitor, has been shown to inhibit BRD4 binding at acetylated histones within the MYC promoter and enhancers, decreasing expression of c … rickman realty west boylston
BRD4 (Bromodomain-Containing Protein 4) Interacts with ... - Circulation
WebMar 21, 2024 · BRD4 regulates downstream gene expression by combining its bromodomains with acetylated histone and lysine residues at histone H3 and H4 sites on chromatin and actively recruits positive transcription extension factor b (P-TEFb) to promote the transcriptional activation of RNA polymerase II (RNAPII) ( 9 ). WebJul 10, 2024 · Bromodomain-containing protein 4 (BRD4) is an epigenetic reader that recognizes histone proteins and acts as a transcriptional regulator to trigger tumor growth and the inflammatory response. The pan-bromodomain and extra-terminal domain (BET) inhibitor, (+)-JQ1 ( 1 ), was reported to inhibit angiogenesis. WebOct 28, 2024 · Computational analysis identified candidate transcription factors participating in the BRD4-regulated transcriptome.
