Application
组织蛋白酶D(来自牛脾)已用于:
- 体外剂量依赖性荧光活性检测。
- 消化体外髓鞘少突胶质细胞糖蛋白(MOG),以研究丙二醛(MDA)修饰MOG的摄取及其对中枢神经系统自身免疫的意义。
- 酶促消化关节软骨的蛋白聚糖部分,以测定两种不同组织结构水平下的软骨弹性模量。
- 组织蛋白酶D活性检测。
Biochem/physiol Actions
核内体-溶酶体天冬氨酸蛋白酶,与乳腺癌转移和阿尔茨海默病有关。 人们发现,在凋亡的人包皮成纤维细胞中,溶酶体释放组织蛋白酶D先于释放细胞色素c和膜电位丧失。

The proinflammatory cytokine IL-1β is a key mediator of inflammatory responses that contribute to and exacerbate brain injury. IL-1β is synthesized by microglia in the brain as an inactive precursor (pro-IL-1β). Cleavage of pro-IL-1β to a mature form is stimulated

ArfGAPs are known to be involved in cargo sorting in COPI transport. However, the role of ArfGAPs in post-Golgi membrane traffic has not been defined. To determine the function of ArfGAPs in post-Golgi traffic, we used small interfering RNA to

The small molecule b-AP15 is a novel inhibitor of proteasome deubiquitination. Recent studies have shown that b-AP15 displays antitumor activity in several preclinical, solid tumor models. In this study, we show that b-AP15 triggers time- and dose-dependent apoptosis of the
