Supplementary information

The C5 molecule also known as complement component 5 is an essential part of the complement system which is part of the immune response. This protein has an approximate molecular weight of 190 kDa and is mainly expressed in the liver circulating in plasma. Upon activation C5 is cleaved into C5a and C5b fragments. The C5b fragment plays an important role in forming the membrane attack complex (MAC) by binding to other complement proteins. The cleavage and activation of C5 are necessary for initiating the assembly of the MAC.
Biological function summary

C5 facilitates the destruction of pathogens by forming the membrane attack complex with other complement proteins such as C6 C7 C8 and C9. C5b acts as a binding site for these proteins leading to a cascade that eventually creates a pore in the pathogen's membrane causing cell lysis. This role in the complement system places C5 as an essential player in innate immunity helping the body eliminate bacteria and foreign cells through direct lysis.

Pathways

C5 functions within the complement pathway specifically in the terminal (lytic) pathway. This pathway has two branches: the classical pathway initiated by antibody-antigen complexes and the alternative pathway activated directly on pathogen surfaces. Both pathways lead to the cleavage of C5 by the C5 convertase resulting in engagement of C5b with C6 C7 C8 and C9 to form the MAC. C5 works closely with other complement proteins including C3 and C4 linking the initial phase of activation to the execution of cell lysis.

C5 has significant connections to conditions such as paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS). These diseases result from dysregulation of the complement system and can lead to excessive activation of C5 and the formation of MAC causing damage to host cells. Eculizumab a monoclonal antibody targeting C5 has been used in treatment by inhibiting C5 activation and preventing the formation of the MAC. This intervention reduces hemolysis and other symptoms associated with these disorders.

Target data

Activation of C5 by a C5 convertase initiates the spontaneous assembly of the late complement components, C5-C9, into the membrane attack complex. C5b has a transient binding site for C6. The C5b-C6 complex is the foundation upon which the lytic complex is assembled.. C5a anaphylatoxin. Derived from proteolytic degradation of complement C5, C5a anaphylatoxin is a mediator of local inflammatory process. Binding to the receptor C5AR1 induces a variety of responses including intracellular calcium release, contraction of smooth muscle, increased vascular permeability, and histamine release from mast cells and basophilic leukocytes (PubMed : 8182049). C5a is also a potent chemokine which stimulates the locomotion of polymorphonuclear leukocytes and directs their migration toward sites of inflammation.
