C1s subsequently activate serum proteins C4 and C2. C4 is cleaved to fragment C4a, which is an anaphylatoxin, and to fragment C4b, which is deposited on the adjacent surfaces. C2 is cleaved to a fragment C2b, and larger fragment C2a, which binds noncovalently to C4b on the target cell membrane. This forms the C4b2a complex |
