Extract of NIH3T3 mouse fibroblasts contains a protease which can cleave epidermal growth factor receptor (EGF receptor). This protease was tentatively named cathepsin X and purified to near homogeneity. The characteristics of cathepsin X were similar to those of cathepsin L and the proteolytic activity of cathepsin X was inhibited by c-Ha-ras gene products.
NIH3T3小鼠成纤维细胞提取物中含有一种能切割表皮生长因子受体(EGF受体)的蛋白酶。这种蛋白酶被暂命名为组织蛋白酶X,并被纯化至接近均一。组织蛋白酶X的特性与组织蛋白酶L相似,且其蛋白水解活性受到c-Ha-ras基因产物的抑制。
