Target Information
Complement component 4-binding protein (C4BP) is a plasma glycoprotein that inhibits the classical pathway of complement activation 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.
Certain Streptococcal strains expressing Ig-binding cell surface molecules (members of the M protein family) can bind to overlapping C4beta binding sites in C4BP, interfering with the classical pathway of complement activation. This bacterial interaction may downregulate complement activation in the bacterial microenvironment, reducing bacterial opsonization and phagocytosis.
