The classical complement activation pathway, like the MELinitiated pathway, involves the generation of a C3-converting complex, C4b2b, through enzymatic activation of C4 and C2. In the C1 complex (C1qr2s2), this specific protease activity is exhibited by C1s after activation of this enzyme by C1r. When C4 is activated, its reactive thiol ester is exposed and C4b binds covalently to nearby amino or hydroxyl groups. The C4-activating abilities of MASP-1 and MASP-2 were compared.|Activation of C4 by Ct sand MASP-2 on western blots. |

H-ficolin binds to PSA, a polysaccharide produced by Aerococcus viridans. C4 was activated by H-ficolin preparations bound to PSA which had been coated on ELISA plates. These results indicate that H-ficolin is a second ficolin which is associated with MASPs and sMAP, and which activates the lectin pathway|Proteolytic activation of complement components by H-ficolin-MASP. |

On the basis of the significant concentration of CL-11 in circulation and CL-11's interaction with various microorganisms and MASP-1 and/or MASP-3, it is conceivable that CL-11 plays a role in activation of the complement system and in the defense against invading microorganisms. |
