体外研究 | 除阻断泛素化外,PYR-41还增加细胞中的总SUMO化。 PYR-41减弱细胞因子介导的核因子-κB活化。 PYR-41还可以防止IκBα的下游泛素化和蛋白酶体降解。此外,PYR-41抑制p53的降解并激活该肿瘤抑制因子的转录活性[1]。 PYR-41(50μM)促进泛素化蛋白质的积累。 PYR-41在4小时后引起Z138细胞中DUB活性的浓度依赖性(10-50μM)下降。即使在最低浓度(10μM)下,PYR-41也有效抑制USP5 DUB活性。 PYR-41有效(10-50μM)抑制各种DUB的活性,确定代表USP9x,USP5,USP14,UCH37和UCH-L3。用DTT和PYR-41共同处理Z138细胞完全消除了泛素化蛋白的积累[2]。 |
激酶实验 | 将兔或小鼠E1(apper 250ng)与32P-遍在蛋白在1x反应缓冲液[50mM Tris(pH 7.4),0.2mM ATP,0.5mM MgCl 2]中在室温下孵育15分钟。在一些实验中,His标记的小鼠E1在进行温育和反应之前与TALON钴亲和树脂结合。将小鼠E1和32P-遍在蛋白加入到1x反应缓冲液中的珠子中,并如E1反应一样温育。将样品在非还原性SDS-PAGE样品缓冲液中加热,并通过SDS-PAGE分离。具有遍在蛋白的硫酯通过Storm PhosphoImager可视化。 |
