一般描述
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。
应用
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。

Kallikrein-related peptidases constitute a single family of 15 (chymo)trypsin-like proteases (KLK1-15) with pleiotropic physiological roles. Aberrant regulation of KLKs has been associated with diverse diseases such as hypertension, renal dysfunction, skin disorders, inflammation, neurodegeneration, and cancer. Recent studies suggested that
