Application
来自大肠埃希菌的重组人组织蛋白酶S已用于组织蛋白酶消化反应。
Biochem/physiol Actions
组织蛋白酶S是一种半胱氨酸蛋白酶,在人B淋巴细胞中II 类复合物的分解中起作用。它具有内蛋白水解活性(endoproteolytic activity ),并有助于处理抗原并将其呈递至免疫细胞,从而影响免疫反应。 组织蛋白酶S参与促进内体-溶酶体途径中受损的或不需要的蛋白的分解。组织蛋白酶S活性调节异常导致各种疾病的产生,如关节炎、癌症和心血管疾病。

General description
注意:1 mU = 1百万单元。
研究领域:细胞信号传导
在大肠埃希菌中表达的重组人组织蛋白酶S,没有标签或融合蛋白。一种优先在巨噬细胞和小胶质细胞中表达的主要溶酶体半胱氨酸蛋白酶。显示通过介导不变(Ii)链降解参与抗原呈递细胞表面上MHC II类分子呈递的抗原肽的加工。组织蛋白酶S的抑制导致抗原呈递受损。
