Dissociation and re-association studies on the interaction domains of mannan-binding lectin (MBL)-associated serine proteases, MASP-1 and MASP-2, provide evidence for heterodimer formation.

Abstract

Activation of the lectin pathway of complement begins with the activation of mannan-binding lectin (MBL)-associated serine proteases, MASP-1 and MASP-2, which are bound to the recognition molecules, MBL and ficolins. MASPs are Ca(2+)-dependent dimers. Dimerization and Ca(2+)-dependent association with the recognition molecules occurs via the first 3 domains… (More)
