A potent complement regulator is disclosed. The complement regulator comprises a complement regulatory region connected by a flexible linker to a multifunctional binding region that enables binding to C3b activation/inactivation products and/or oxidation end products, as well as to polyanionic surface markers on host cells. An embodiment of the invention utilizes factor H SCRs 1-4 as the complement regulatory region and factor H SCRs 19 and 20 as the multifunctional binding region, linked together by a poly-Gly linker at least 12 residues in length. Pharmaceutical compositions comprising the complement regulator and methods of using the complement regulator are also disclosed.
