应用
人肾细胞产生的尿激酶已被用作消化混合物的成分，用于三维纤维蛋白培养。也用于纤溶酶原激活试验。
生化/生理作用
尿激酶可促进肾肿瘤细胞的增殖。
尿激酶是一种蛋白酶，能裂解纤溶酶原形成纤溶酶。与细胞表面受体 (uPAR) 结合，在组织重塑过程中调节细胞粘附和迁移，并激活细胞内信号通路。尿激酶由三个结构域组成：与表皮生长因子同源的氨基末端结构域通过中央圈形区结构域连接到羧基端的蛋白酶结构域。
物理属性
主要活性成分是尿激酶的低分子量形式，由 2,000 道尔顿的 A 链和 30,400 道尔顿的 B 链通过巯基键连接而成。
供应的冻干粉，含有人血白蛋白、甘露醇和 NaCl。
其他说明
注：当人纤维蛋白溶酶原作为底物时，活性更高。

The K+-sparing diuretic amiloride shows off-target anti-cancer effects in multiple rodent models. These effects arise from the inhibition of two distinct cancer targets: the trypsin-like serine protease urokinase-type plasminogen activator (uPA), a cell-surface mediator of matrix degradation and tumor cell
