It is sometimes referred to as factor B complement and its gene identifier is often referenced as KY21 NNL or factor B 1001. Factor B has a molecular mass of approximately 93 kDa. It is mainly expressed in the liver but can also be found in blood plasma in its inactive form as part of the innate immune response.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nFactor B is involved in the alternative complement pathway which serves as a part of the body's defense mechanism. It participates in the formation of the C3 convertase together with factor D and properdin initiating a cascade that can lead to the opsonization and elimination of pathogens. Factor B undergoes cleavage by factor D which generates the Ba and Bb fragments with Bb functioning as a serine protease within the C3 convertase complex.\u003cbr\u003e\nPathways\u003cbr\u003e\nFactor B contributes to the complement system interacting notably in the alternative and lectin pathways. In these pathways Factor B associates with proteins like complement component C3. The alternative pathway is activated on microbial surfaces independent of antibodies. The involvement of Factor B in these pathways illustrates its role in pathogen recognition and further highlights its cooperation with complement proteins such as C3 and properdin.\u003cbr\u003e\nFactor B has been associated with atypical hemolytic uremic syndrome (aHUS) a rare and serious disease affecting kidney function. Factor B involvement in aHUS links it to abnormal complement activation leading to a pathological condition. Additionally Factor B connects to age-related macular degeneration (AMD) a disorder where complement pathway genetic variations including those involving Factor B have shown associations. Understanding interactions with other complement components such as factor H helps to elucidate its role in these diseases.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843539652777,"sku":"ab300318","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab300318","provider":"Iright","version":"1.0","type":"link"}
