BRD4
BRD4,即溴结构域蛋白4,别名BRD4。BRD4是一种属于溴结构域和超末端结构域(BET)家族的蛋白,主要通过识别乙酰化组蛋白来调节基因表达。BRD4的作用机制主要涉及其与转录因子的相互作用。BRD4通过其两个溴结构域(BD1和BD2)结合乙酰化的组蛋白,定位于目标基因的启动子或增强子区域,促进相关基因的转录。此外,BRD4还通过招募转录延伸因子和其他调节因子,增强RNA聚合酶II的活性,从而促进基因的转录伸长。BRD4在细胞周期、增殖和凋亡等生理过程中起着关键作用。研究表明,BRD4的异常表达与多种恶性肿瘤的发生发展相关,包括急性髓系白血病、多发性骨髓瘤、乳腺癌和胶质母细胞瘤等。BRD4不仅参与肿瘤细胞的增殖和转移,还在DNA损伤修复和端粒维持中发挥重要作用。因此,BRD4成为了癌症治疗的一个重要靶点。

All lanes: BRD4 antibody at 1:1500
Secondary
Goat polyclonal to rabbit IgG at 1/50000 dilution
Predicted band size: 153, 81, 89 kDa

IHC image of CSB-RA152430A0HU diluted at 1:100 and staining in paraffin-embedded human brain tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4℃ overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.
