Mannan-binding lectin serine protease 1 also known as mannose-associated serine protease 1 (MASP-1) is an enzyme that in humans is encoded by the MASP1 gene.MASP-1 is involved in the lectin pathway of the complement system and is responsible for cleaving C4 and C2 to form C4b2a a C3-convertase.MASP-1 is a serine protease that functions as a component of the lectin pathway of complement activation. The complement pathway plays an essential role in the innate and adaptive immune response.
