Supplementary information

Complement factor B also known as CFB protein is a component of the complement system. It plays an important role in the alternative pathway. This protein with a molecular mass of approximately 93 kDa is produced mainly in the liver and expresses in various tissues throughout the body. Factor B comprises several domains including the von Willebrand factor type A domain essential for its activity. CFB engages in protein-protein interactions important for the function of the complement cascade.
Biological function summary

Complement factor B is essential in the immune system. It participates in the formation of the C3 convertase complex which is an important step in the amplification of the complement cascade. This protein contributes to the opsonization and clearance of pathogens assisting in the immune response. CFB binds with complement component C3b to participate in the alternative pathway which does not require antibody presence for activation.

Pathways

Complement factor B is part of the innate immune pathway. It helps mediate the alternative complement pathway acting as an amplifier of immune responses. This pathway interacts closely with the classical and lectin pathways ensuring a versatile defense mechanism. Factor D for example also plays a complementary role by cleaving factor B when bound to C3b to form C3 convertase a critical step in propagating the immune response.

Complement factor B associates with kidney-related diseases like atypical hemolytic uremic syndrome (aHUS). Mutations in CFB can lead to deregulated complement activation contributing to pathological conditions like age-related macular degeneration (AMD). The relationship with protein C3 is important in these disorders as both factor B and C3 engage in interactions that when dysfunctional influence disease outcomes. Understanding these interactions can help develop targeted therapies such as anti-complement agents to modulate the complement system in these diseases.

Target data

Factor B which is part of the alternate pathway of the complement system is cleaved by factor D into 2 fragments : Ba and Bb. Bb, a serine protease, then combines with complement factor 3b to generate the C3 or C5 convertase. It has also been implicated in proliferation and differentiation of preactivated B-lymphocytes, rapid spreading of peripheral blood monocytes, stimulation of lymphocyte blastogenesis and lysis of erythrocytes. Ba inhibits the proliferation of preactivated B-lymphocytes.
