Caption: The animation shows how the MASP-2 (blue) attaches itself to the complement protein C4 (orange), and the structural rearrangements that occur in the C4 due to this. Note that although the MASP-2 recognizes only a relatively small part of the C4, rearrangements take place in large areas of the C4 molecule.
