产品介绍
来自人胎盘的组织蛋白酶 B 被用于 体外 修饰的髓鞘少突胶质细胞糖蛋白 (MOG) 的消化。也用于测定半胱氨酸蛋白酶抑制药的作用。组织蛋白酶 B 是一种溶酶体半胱氨酸蛋白酶,能水解蛋白质,对肽键具有广泛的特异性。组织蛋白酶 B 可能是一个有用的工具在阿尔茨海默氏症的研究,因为它可能有一个作用的自然防御疾病 。组织蛋白酶 B 可用于裂解前半胱天冬酶 1 和前半胱天冬酶 11,并诱导洋地黄皂苷透化细胞凋亡。应用: 组织蛋白酶 B 由基因 CTSB 编码,位于人类染色体 8p23.1组织蛋白酶 B 是半胱氨酸蛋白酶家族的溶酶体蛋白水解酶。它存在于所有哺乳动物细胞中。它是细胞内蛋白质周转所必需的。 Cathepsin B is encoded by the gene CTSB and is located in the human chromosome at 8p23.1. Cathepsin B is a lysosomal proteolytic enzyme of cysteine protease family. It is present in all mammalian cells. It is essential for the intracellular protein turnover. Application: Cathepsin B from human placenta has been used in the in vitro digestion of modified myelin oligodendrocyte glycoprotein (MOG). It has also been used in determining the effect of cysteine protease inhibitors. Cathepsin B is a lysosomal cysteine proteinase which hydrolyzes proteins with a broad specificity for peptide bonds. Cathepsin B may be a useful tool in Alzheimer′s research, as it may have a role in the natural defense against the disease . Cathepsin B may be used to cleave procaspase 1 and procaspase 11, and to induce apoptosis in digitonin-permeabilized cells.
生化机理
在小分子底物中,组织蛋白酶 B 优先裂解在 Arg-Arg 键的碳氧酰基侧。已证明组织蛋白酶 B 可降解 β-淀粉样前体蛋白变成无害的片段 。抑制组织蛋白酶 B 可以限制乳腺癌骨转移 。已发现组织蛋白酶 B 可裂解前半胱天冬酶 1 和前半胱天冬酶 11,并诱导洋地黄皂苷透化细胞凋亡。组织蛋白酶 B 从细胞质转位至细胞核有助于胆盐诱导大鼠肝细胞凋亡。PC12 细胞在凋亡诱导后 12~24 小时,组织蛋白酶 B 的水平显著降低。
