甘露聚糖结合凝集素丝氨酸肽酶1抗体产品介绍

甘露糖结合凝集素(MBL)是补体系统的原有成分，是由肝脏合成的C型凝集素并游离在血清中，也是钙依赖性糖结合蛋白。
MBL可识别和结合病原微生物表面的甘露糖、岩藻糖和N-乙酰葡糖胺等糖结构并首先与病原微生物的糖类配体结合，随后构象发生变化，激活与之相关联的MBL相关的丝氨酸蛋白激酶(MASP)，两种MASP(MASP1、MASP2)具有与活化的C1s类似的生物学活性，其中MASP2可水解C4和C2分子，MASP1则可直接切割C3，而形成C3转化酶，以至补体顺序激活，这是补体激活的MBL途径，这种补体顺序的被激活在机体的固有性免疫防御中发挥重要作用。
MASP is a component of the bactericidal ra-reactive factor rarf which specifically binds to RA and R2 polysaccharides expressed by certain enterobacteria. It triggers the activation of complement cascade by activating the C4 and C2 components. It activates the C4 component by cleaving the alpha-chain of C4. The alternative-splicing product from MASP1 gene is called MASP3. MASP1 is associated with smaller MBL oligomers whereas MASP3 is found on larger oligomers. The substrate of MASP3 is unknown.

Also known as:
CRARF; EC 3.4.21; Mannan binding lectin serine protease 1; Mannose binding protein associated serine protease; MASP; PRSS 5; Ra reactive factor serine protease p100; RaRF; Serine protease 5
