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.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nThe '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.\u003cbr\u003e\nPathways\u003cbr\u003e\nThe '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.\u003cbr\u003e\n'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.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46851916464297,"sku":"ab249454","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab249454","provider":"Iright","version":"1.0","type":"link"}
