Secondary Accession Numbers Not Available
Name Mannan-binding lectin serine protease 2
Description Not Available
Synonyms
  1. MASP-2
  2. MBL-associated serine protease 2
  3. Mannan-binding lectin serine protease 2 A chain
  4. Mannan-binding lectin serine protease 2 B chain
  5. Mannose-binding protein-associated serine protease 2
Gene Name MASP2
Protein Type Enzyme
Biological Properties
General Function Involved in calcium ion binding
Specific 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
