Target Information
Complement component 4-binding protein (C4BP) is a plasma glycoprotein that inhibits the classical pathway of complement activation, which is mediated through antibody targeting of foreign antigen. Structurally, C4BP is a disulfide-linked, multimeric protein composed of seven alpha chains and one beta chain. It functions as a cofactor for C3beta inactivator in the cleavage of C3beta and accelerates the decay of C4betaC2alpha (C3 convertase) by acting as a cofactor in the cleavage of C4beta by factor I.
Streptococcal strains expressing Ig-binding surface molecules (M protein family) can bind overlapping C4beta binding sites in C4BP, interfering with the classical complement activation pathway. Bacteria-bound C4BP may represent an evolved mechanism to downregulate complement activation in the bacterial microenvironment, reducing opsonization and phagocytosis.
