C4BPB Rabbit anti-Human, Mouse, Polyclonal, Proteintech
Rabbit Polyclonal Antibody
Supplier: Proteintech Group Inc 158371AP150UL
Description
C4BP is composed of two polypeptides (alpha and beta chains), which have molecular weights of 70 and 45 kDa, respectively. This polyclonal antibody is raised against the C4BP beta chain (C4BPB).
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 that is composed of seven alpha chains and one beta chain. C4BP 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 that express Ig-binding cell surface molecules, which are members of the M protein family, can bind to overlapping C4beta binding sites in C4BP and therefore, interfere with the classical pathway of complement activation. Bacteria-bound C4BP may be an evolved mechanism that downregulates complement activation in the bacterial host microenvironment, thereby reducing the occurrences of bacterial opsonization and phagocytosis.Specifications
