摘要: 甘露糖结合凝集素相关的丝氨酸蛋白酶(mannan binding lectin-associated serine protease,MASP)和甘露糖结合凝集素(mannan binding lectin,MBL)是补体激活的凝集素途径中的关键因子,发挥着至关重要的作用。MBL或纤维胶凝蛋白(ficolin)分子通过C端糖识别域(carbohydrate recognition domain,CRD)与病原微生物表面的糖类结构结合,其胶原样区(collagen-like region,CLR)与MASP结合,使无活性的MASP转换为活性MASP,从而激活补体凝集素途径。

Abstract: MBL-associated serine protease (MASP) and mannan-binding lectin (MBL) are key factors of the lectin pathway of complement activation and play an important role in the defense.MBL or ficolin can form complexes with sugars presented on pathogens through its carbohydrate recognition domain (CRD) and its collagen-like region (CLR) can recognize and binding to MASP. MBL can activity the zymogens of MASP which is a key enzyme and activate the complement cascade through lectin pathway.

Key words: MASP; the lectin pathway; molecular structure; function
