SwePub titelinformation: High complement factor I activity in the plasma of children with autism spectrum disorders.
C3b is proteolytically generated from C3 by cleavage of the C3a-C3b peptide bond in the protein by C3 convertase. C3b can bind covalently, via its reactive thioester, to cell surface carbohydrates or immune aggregates. Macrophages and neutrophils recognize C3b by the complement receptor 1 (CR1, CD35).
and results in generation of fluid phase anaphylatoxins C3a and C5a, and surface-bound C3b and iC3b. al. 2004. C3a and C3b Activation Products of the Third. Component of Complement (C3) Are Critical for.
and Reid, K.B.M. (1995)). Initiation of each pathway generates proteolytic enzyme complexes (C3 convertases) which are bound to the target surface. The human C3b receptor (CR1) is a polymorphic glycoprotein which functions regulating the complement system by inhibiting the activation of C3 and C5, through its effect on their convertases, and serving as cofactor for factor I in mediating the degradation of C3b to … Complement C3b/C3d and cell surface polyanions are recognized by overlapping binding sites on the most carboxyl-terminal domain of complement factor H J Immunol . 2002 Dec 15;169(12):6935-44. doi: 10.4049/jimmunol.169.12.6935.

C3b is the larger of two elements formed by the cleavage of complement component 3, and is considered an important part of the innate immune system.
Complement component 3 (C3) plays a central role in the activation of the complement system. C3 cleavage by C3-convertase produces C3b and iC3b. C3b leads to an inflamatory response and also covalently binds to microbial cell surfaces aiding in opsonization of the microbe. From the laboratory of Ronald P. Taylor, PhD, University of Virginia.
Complement C3b (PDB ID: 2HR0) is a protein found in the human complement system, which is a component of the immune system.The human complement system is implicated in innate and adaptive immune response, particularly in recruiting phagocytic cells to incorporate pathogens in order to destroy them and in linking innate and adaptive immunity (1). Complement C3b Antibodies Inactive complement component 3b (iC3b) is a 42kDa neoantigen present in blood serum.
The complex of C4bC2bC3b forms an opsonic macromolecular coat on the target cells and makes it susceptible to immune adherence by the C3b receptor on the phagocytic cells. C4b C2b C3b acts as a C5 convertase and cleaves C5 into C5a and C5b.
During normal complement activation, much more C3b is fixed than C4b, and it is unlikely that C4b has an important role in receptor-mediated adhesion or ingestion mechanisms. C1q also binds, via its collagenous region, to a receptor, a widely distributed 60 kDa species (C1q-R). The C3b complement protein deposited on the pathogen's surface is broken down into C3d and C3c by Factor I alternative pathway C3d then binds to the CR2 receptor on B cell cross links the ag/Ig binding initiation of signaling through CD19 and activation of B cell. Complement C3b, Human, is a native C3b complement component. It is a glycoprotein composed of the modified C3-α chain (αʹ) (M.W.
