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。

A subtelomeric region, 4q35.2, is implicated in facioscapulohumeral muscular dystrophy (FSHD), a dominant disease thought to involve local pathogenic changes in chromatin. FSHD patients have too few copies of a tandem 3.3-kb repeat (D4Z4) at 4q35.2. No phenotype is associated

Hereditary angioedema (HAE) is a debilitating, potentially fatal disease characterized by variable and unpredictable acute attacks of swelling affecting the subcutaneous tissue and mucosa. It is an autosomal dominant disorder resulting from a genetic deficiency of functional C1-esterase inhibitor. Available
