生化/生理作用
丝氨酸和半胱氨酸蛋白酶抑制剂。抑制纤溶酶、胰蛋白酶、木瓜蛋白酶、钙蛋白酶和组织蛋白酶 B。不抑制胃蛋白酶、组织蛋白酶 A 和 D、凝血酶或 α-糜蛋白酶。有效浓度 10-100 μM。已有许多研究使用亮肽素预防由声过度刺激或耳毒性抗生素庆大霉素引起的听力丧失。(耳蜗毛细胞的丢失被认为是由钙蛋白酶介导的。)
分析说明
亮肽素在溶液中形成互变异构体,因此HPLC分析时会出现多个峰。大多数污染性肽是外消旋化的亮肽素。

Cells produce two broad classes of extracellular vesicles (EVs), exosomes and microvesicles (MVs). Exosomes are 30-150 nm vesicles derived from multivesicular bodies, while MVs are 200-1,000 nm vesicles that pinch off from plasma membranes. Reliable isolation of EVs is crucial to understand
Pharmacologic inhibition of site 1 protease activity inhibits sterol regulatory element-binding protein processing and reduces lipogenic enzyme gene expression and lipid synthesis in cultured cells and experimental animals.

Glucocerebrosidase (GCase), encoded by the GBA gene, degrades the ubiquitous glycosphingolipid glucosylceramide. Inherited GCase deficiency causes Gaucher disease (GD). In addition, carriers of an abnormal GBA allele are at increased risk for Parkinson's disease. GCase undergoes extensive modification of its
