Compstatin, a peptide inhibitor of complement, exhibits species-specific binding to complement component C3.

Abstract excerpt

Although activation of complement protein C3 is essential for the generation of normal inflammatory responses against pathogens, its unregulated activation during various pathological conditions leads to host cell damage. Previously we have identified a 13-residue cyclic peptide, Compstatin, that inhibits C3 activation. In this study, we have examined the species-specificity of Compstatin. Bimolecular interaction...
