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. Source: Recombinant protein corresponding to aa16-686 from human Mannan-binding lectin serine protease 2, fused to 6X His-Tag at C-terminal, expressed in Baculovirus.
