General description
本品取自牛红细胞。非重组产品。独家生产工艺。包含热处理、色谱和透析法纯化步骤。
研究领域:癌症
泛素是一种高度保守的调控蛋白。它存在于所有真核细胞中,在包括酵母、人类和植物在内的所有生命形式中几乎是相同的。泛素结构包含7个赖氨酸残基和一个N末端,这些都是泛素化的靶点。

Application
来自牛红细胞的泛素已用于研究外源性泛素在慢性β肾上腺素受体(β-AR)刺激的心肌重构中的作用。它还被用作测试核因子kappa-B激酶亚基β(IKKβ)泛素化的抑制剂。
来自牛红细胞的泛素可用于体外泛素化检测。该产品还可以用作蛋白质印迹的标记物。

Biochem/physiol Actions
泛素化是泛素蛋白与底物蛋白结合的翻译后修饰过程。泛素化在细胞凋亡、蛋白质加工、免疫反应、DNA修复等生物学过程中对细胞信号传导的调控起着重要作用。泛素化通过泛素-蛋白酶体途径介导蛋白质降解。泛素化作用涉及多种细胞信号传导途径。多聚泛素化可调节炎症信号传导途径中NF-κ-B抑制剂α(IkB-α)的信号激活。在很多疾病中都可观察到泛素水平的升高,比如寄生虫病和过敏性疾病、酒精性肝病、ii型糖尿病、2-微球蛋白淀粉样变tβ2-微球蛋白淀粉样变以及慢性血液透析等。
Preparation Note
牛红细胞中的泛素可以1 mg/ml的量溶于水中,产生澄清无色的溶液。

When Saccharomyces cerevisiae cells are exposed to high hydrostatic pressure, tryptophan permease Tat2 is degraded in a manner dependent on Rsp5 ubiquitin ligase. Consequently, cell growth is arrested in tryptophan auxotrophic strains. Here we show that of 17 ubiquitin-specific protease

β-Adrenergic receptor (β-AR) stimulation increases extracellular ubiquitin (UB) levels, and extracellular UB inhibits β-AR-stimulated apoptosis in adult cardiac myocytes. This study investigates the role of exogenous UB in chronic β-AR-stimulated myocardial remodeling. l-Isoproterenol (ISO; 400 μg·kg(-1)·h(-1)) was infused in mice
