MeSH definition : Serum serine proteases which participate in COMPLEMENT ACTIVATION. They are activated
when complexed with the MANNOSE-BINDING LECTIN, therefore also known as Mannose-binding
protein-Associated Serine Proteases (MASPs). They cleave COMPLEMENT C4 and COMPLEMENT
C2 to form C4b2a, the CLASSICAL PATHWAY C3 CONVERTASE.;
