鼻咽癌相关转录调节蛋白抗体产品介绍 This gene encodes a protein which is a member of the bromodomain-containing protein family. The product of this gene has been identified as a component of one form of the SWI/SNF chromatin remodeling complex, and as a protein which interacts with p53 and is required for p53-dependent oncogene-induced senescence which prevents tumor growth. Pseudogenes have been described on chromosomes 2, 3, 6, 13 and 14. Alternative splicing results in multiple transcript variants.
Function : Acts both as coactivator and as corepressor. May play a role in chromatin remodeling. Activator of the Wnt signaling pathway in a DVL1-dependent manner by negatively regulating the GSK3B phosphotransferase activity. Induces dephosphorylation of GSK3B at 'Tyr-216'. Down-regulates TRIM24-mediated activation of transcriptional activation by AR (By similarity). Transcriptional corepressor that down-regulates the expression of target genes. Binds to target promoters, leading to increased histone H3 acetylation at 'Lys-9' (H3K9ac). Binds to the ESR1 promoter. Recruits BRCA1 and POU2F1 to the ESR1 promoter. Coactivator for TP53-mediated activation of transcription of a set of target genes. Required for TP53-mediated cell-cycle arrest in response to oncogene activation. Promotes acetylation of TP53 at 'Lys-382', and thereby promotes efficient recruitment of TP53 to target promoters. Inhibits cell cycle progression from G1 to S phase.
Subunit : Interacts with TRIM24, PTPN13 and DVL1. Identified in a complex with SMARCA4/BRG1, SMARCC1/BAF155, SMARCE1/BAF57, DPF2/BAF45D and ARID2, subunits of the SWI/SNF-B (PBAF) chromatin remodeling complex (By similarity). Interacts with IRF2 and HNRPUL1. Interacts (via N-terminus) with TP53. Interacts (via C-terminus) with EP300. Interacts with BRCA1. Interacts (via bromo domain) with histone H3 (via N-terminus) acetylated at 'Lys-14' (H3K14ac). Has low affinity for histone H3 acetylated at 'Lys-9' (H3K9ac). Has the highest affinity for histone H3 that is acetylated both at 'Lys-9' (H3K9ac) and at 'Lys-14' (H3K14ac). Has very low affinity for non-acetylated histone H3. Interacts (via bromo domain) with histone H4 (via N-terminus) acetylated at 'Lys-8' (H3K8ac) (in vitro).
Subcellular Location : Isoform 2: Nucleus.
Similarity : Contains 1 bromo domain.

BRD7可能参与了基因转录调控,是一个核转录调节蛋白。经研究发现BRD7可能是通过Ras/MEK/ERK和Rb/E2F两条通路影响细胞周期的进程,使细胞停滞于G0/G1期,BRD7具有阻止细胞周期进程的作用。BRD7蛋白尤其是在鼻咽癌的发病过程中发挥了十分重要作用,BRD7基因的过表达可通过调节MAPK及Wnt信号通路抑制鼻咽癌的生长,并将鼻咽癌阻滞在G1/S期。
纯度:在实验的任何阶段,确定抗体溶液纯度的最简单方法是取一部分样本进行SDS-PAGE电泳。凝胶可用考马斯亮蓝染色(灵敏度为0.1—0.5ug/带)或银染(灵敏度1~l0ug/带)。
定量:如果抗体还不纯,有一个快捷的定量方法,即通过SDS-PAGE电泳分离出轻、重链,然后和已知的标准染色带比较。如果需要分析许多样本,用免疫测定法对抗体定量较容易。如果抗体是经过纯化的,可通过测蛋白总量代替上述两种方法,有一简单的方法,即紫外吸收法。鼻咽癌相关转录调节蛋白抗体的量可通过测280nm处的吸收值来测(10D大致相当于0.75mg/m1的纯化抗体)。
抗原结合活性:一般说来,纯化方法不会引起抗原结合活性的改变。用蛋白G或蛋白A树脂很少导致抗体活性丧失。然而,如果最终抗体产物的作用不如原来所预料的好,检测抗体纯化过程所丢失的活性就极为重要。用一系列滴定法比较纯化的抗体和其原材料的活性,以标定每一步中的总抗体量,这将有助于较好的估计通过纯化所丢失的活性。
