一般說明

Kallikrein肽酶属于15个高度保守的胰蛋白酶或胰凝乳蛋白酶家庭的成员。血浆激肽释放酶(PK)是一种来源于血浆前激肽释放酶的丝氨酸蛋白酶,也是一种在血液循环中含量较高的酶原。KLKB1基因位于人染色体4q35.2上。

應用

从人血浆中提取的激肽释放酶已用于:

  • 培养人肝癌细胞系
  • 研究其对来自脑膜炎奈瑟氏菌的奈瑟球菌肝素结合抗原(NHBA)的裂解作用
  • 肽酶抑制分析

生化/生理作用

血浆激肽释放酶(PK)参与缓激肽的合成,可维持血液代谢物水平和高血压。它还参与凝血因子XII的激活,促进炎症和内源性凝血途径。PK控制心血管系统中的蛋白水解级联反应,如激肽酶激肽系统、肾素血管紧张素系统、纤维蛋白溶解系统和补体旁路等。它参与胰高血糖素样肽-1(GLP-1)和神经肽Y(NPY) 的裂解,这表明血浆激肽释放酶可能会影响代谢和糖尿病。

單位定義

外觀

溶于20 mM Tris-HCl (pH 7.8)和100 mM NaCl的溶液中。
