Product Detail	MASP2, MBL associated serine protease 2, is a serum protease that plays an important role in the activation of the complement system via mannose-binding lectin (MBL). Binding of MBL to carbohydrate groups triggers MASP2 activation by auto-catalytic cleavage which leads to cleavage of C2 and C4, leading to their activation and to the formation of C3 convertase. MASP2 also binds to L-Ficolin and H-Ficolin, and when the complex binds pathogens the MASP is activated. Low MBL levels in serum are associated with increased susceptibility to infection, and an Asp105Gly mutation in MASP2 is associated with low MASP2 levels in serum. Reduced functional levels of MBL are also postulated to be associated with generation of autoantibodies in systemic lupus erythematosus, acting through a decreased clearance of apoptotic material. A truncated form of MASP2 that constitutes the amino 185 residues, Map19 is also a component of the MBL-MASP-1 complex. Function: Serum protease that plays an important role in the activation of the complement system via mannose-binding lectin. After activation by auto-catalytic cleavage it cleaves C2 and C4, leading to their activation and to the formation of C3 convertase. Subunit: Homodimer; disulfide-linked. Binds MBL2. Isoform 2 binds to MASP1. Binds SERPING1. Dimerization and MBL2 binding requires calcium ions. Subcellular Location: Secreted. Tissue Specificity: Plasma. Post-translational modifications: The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate and asparagine is (R) stereospecific within EGF domains. Activated by cleavage after Arg-444. The uncleaved zymogen is inactive towards synthetic substrates, but has sufficient activity to effect autocatalytic cleavage. DISEASE: Defects in MASP2 are the cause of MASP2 deficiency (MASPD) [MIM:613791]. MASPD is a disorder that results in autoimmune manifestations, recurrent severe infections, and chronic inflammatory disease. Similarity: Belongs to the peptidase S1 family. Contains 2 CUB domains. Contains 1 EGF-like domain. Contains 1 peptidase S1 domain. Contains 2 Sushi (CCP/SCR) domains.
