Functional estimation of mannose binding lectin associated serine protease (MBL-MASPs) in human serum.
BACKGROUND & OBJECTIVE Mannose binding lectin (MBL), a C-type or Ca(2+) dependent lectin, plays a major role in lectin pathway of complement activation. MBL deficiency/insufficiency is associated with susceptibility to many infections. It is important to know the association of functional lectin levels with disease condition. Therefore, we carried out this study to develop a simple assay to est...
متن کاملInteraction of C1q and mannan-binding lectin (MBL) with C1r, C1s, MBL-associated serine proteases 1 and 2, and the MBL-associated protein MAp19.
Mannan-binding lectin (MBL) and C1q activate the complement cascade via attached serine proteases. The proteases C1r and C1s were initially discovered in a complex with C1q, whereas the MBL-associated serine proteases 1 and 2 (MASP-1 and -2) were discovered in a complex with MBL. There is controversy as to whether MBL can utilize C1r and C1s or, inversely, whether C1q can utilize MASP-1 and 2. ...
متن کاملThe emerging roles of mannose-binding lectin-associated serine proteases (MASPs) in the lectin pathway of complement and beyond.
Mannose-binding lectin (MBL)-associated serine proteases (MASPs) are the enzymatic constituents of the lectin pathway of the complement system. They are complexed with large pattern recognition molecules (PRMs) such as MBL, other collectins, and ficolins. The main function of two of the three MASPs has crystallized lately: MASP-1 autoactivates first, then it activates MASP-2, and finally both p...
متن کاملMannan-binding lectin (MBL) and MBL-associated serine protease-2 in children with cancer.
QUESTIONS UNDER STUDY Mannan-binding lectin (MBL) and MBL-associated serine protease-2 (MASP-2) are two key components of the lectin-pathway of complement-activation. Information on the potential role of lectin-pathway components in carcinogenesis versus immune surveillance of cancer is scarce. This study aimed to determine if serum concentrations of MBL and MASP-2 differ between children with ...
متن کاملBiochemistry and genetics of mannan-binding lectin (MBL).
Mannose- or mannan-binding lectin (MBL) is a member of the collectin protein family, which includes lung surfactant proteins SP-A and SP-D. Each member consists of similar or identical polypeptide chains with a region of collagen-like sequence followed by a C-type lectin domain. The polypeptides associate in threes to form a subunit containing a collagen-like helix, with three clustered lectin ...
