Biological function summary
Factor 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.
Pathways
Factor 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.
