USP8 蛋白, Human (sf9, His, GST)

USP8 is a key hydrolase in cellular regulation and plays a crucial role in protein turnover by efficiently deubiquitinating proteins and preventing degradation. Its activity spans "Lys-48" and "Lys-63" linked ubiquitin chains, highlighting its versatility. USP8 Protein, Human (sf9, His, GST) is the recombinant human-derived USP8 protein, expressed by Sf9 insect cells, with N-His and N-GST labeled tag.

USP8 是一种在细胞调节中发挥关键作用的水解酶，通过有效去除蛋白质中的缀合泛素，防止其降解，在蛋白质周转中发挥着关键作用。这种酶促作用延伸至“Lys-48”和“Lys-63”连接的泛素链，展示了其在调节泛素动力学方面的多功能性。USP8 的催化活性在 M 期显着增强，强调了其细胞周期依赖性调节功能。该酶错综复杂地参与各种细胞过程，包括细胞增殖和对血清刺激的反应，这是进入 S 期所必需的。此外，USP8 还涉及 T 细胞无反应性的调节、STAM2 和 RASGRF1 等蛋白质的稳定以及内体动力学、货物分类和膜运输的调节。它在控制内体泛素化方面的作用对于维持细胞器的形态至关重要。USP8 进一步对多种途径产生影响，包括顶体生物发生、EGFR 降解、MAPK 信号传导以及 BACE1 介导的 APP 裂解和淀粉样蛋白形成的调节。USP8 的多方面功能凸显了其在维持细胞稳态和协调各种信号级联中的重要性。
