補足情報

This supplementary information is collated from multiple sources and compiled automatically.

The 'C4b' protein also known as the 'C4b complement' plays a significant role in the immune system. This protein is a part of the larger complement system specifically as a segment derived from the cleavage of the native 'C4 complement'. It has an estimated molecular mass of about 200 kDa. The 'C4b' protein is prominently expressed on the surface of cells and in body fluids where the immune response is active. As an important player in the complement pathway it binds covalently to foreign particles labeling them for destruction or removal by immune cells.

Biological function summary

The 'C4b complement' interacts with various other components of the immune system. It is particularly involved in the formation of the C3 and C5 convertase complexes which are essential for the opsonization and activation cascade leading to pathogen elimination. Its attachment to cellular surfaces provides a docking point for proteins such as C2 facilitating the further cleavage and progression of the complement cascade. This interaction is critical for driving the classical and lectin pathways of complement activation.

Pathways

The 'C4b protein' is integral to the classical pathway of complement activation as well as to the lectin pathway. It associates with proteins like C1s C1q and factor B forming complexes that execute various stages of immune defenses. By forming C3 and C5 convertase 'C4b' not only promotes phagocytosis but also inflammation and cell lysis through membrane attack complexes. These processes underlie the body's ability to address microbial invasions efficiently.

'C4b complement dysregulation' can lead to autoimmune conditions such as systemic lupus erythematosus (SLE) and type 1 diabetes. In SLE reduced or malfunctional 'C4b' increases susceptibility to infections and triggers inappropriate immune responses. It can also correlate with the deficiency of related proteins like C2 which further impairs the complement system. These associations indicate that proper regulation of 'C4b' is essential for maintaining immune system stability and preventing overactive immune responses.

Precursor of non-enzymatic components of the classical, lectin and GZMK complement pathways, which consist in a cascade of proteins that leads to phagocytosis and breakdown of pathogens and signaling that strengthens the adaptive immune system.. Complement C4b-B. Non-enzymatic component of C3 and C5 convertases (By similarity). Generated following cleavage by complement proteases (C1S, MASP2 or GZMK, depending on the complement pathway), it covalently attaches to the surface of pathogens, where it acts as an opsonin that marks the surface of antigens for removal (By similarity). It then recruits the serine protease complement C2b to form the C3 and C5 convertases, which cleave and activate C3 and C5, respectively, the next components of the complement pathways (PubMed : 8538770). Complement C4b-B isotype catalyzes the transacylation of the thioester carbonyl group to form ester bonds with carbohydrate antigens, while C4b-A isotype is responsible for effective binding to form amide bonds with immune aggregates or protein antigens (PubMed : 8538770).. C4a anaphylatoxin. Putative humoral mediator released following cleavage by complement proteases (C1S, MASP2 or GZMK, depending on the complement pathway). While it is strongly similar to anaphylatoxins, its role is unclear. Was reported to act as a mediator of local inflammatory process; however these effects were probably due to contamination with C3a and/C5a anaphylatoxins in biological assays.
