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 mint Derived from proteolytic degradation of complement C5, C5 anaphylatoxin is a mediator of local inflammatory process. It induces the contraction of smooth muscle, increases vascular permeability and causes histamine release from mast cells and basophilic leukocytes. C5a also stimulates the locomotion of polymorphonuclear leukocytes (chemokinesis) and direct their migration toward sites of inflammation (chemotaxis) Defects in C5 are the cause of complement C5 deficiency [MIM:609536]. Patients with dysfunction of C5 display a propensity for severe recurrent infections Genetic variation in C5 can be associated with susceptibility to liver fibrosis [MIM:120900]. Liver fibrosis is a common consequence of all chronic liver diseases, irrespective of etiology. Common C5 variants can influence the progression and severity of fibrogenesis A7589E352F74672A p01031-pro_0000005989 Complement C5 alpha' chain C3 and PZP-like alpha-2-macroglobulin domain-containing

assertion IPI inferred from physical interaction Involved in the complement system. The complement system is a part of the innate immune system that enhances (complements) the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism. The complex is formed after C5 cleavage by C5 convertase into C5a and C5b. C5b has a transient binding site for C6. Without C6 binding, C5b will irreversibly decay to a state incapable of binding C6. The complex initiates pore formation via the sequential recruitment of homologous proteins: C7, C8, and 12-18 copies of C9, each of which comprises a central MAC-perforin domain flanked by auxiliary domains. Activation of the complement system results in formation of membrane attack complexes (MACs), pores that disrupt lipid bilayers and lyse bacteria and other pathogens. Heterotrimer Bimolecular complex of Mr = 300,000. C5b grabs the top of C6 like a pair of pincers. The C-terminal region of C6 forms the major interface with C5b. The C5b-C6 interface buries 3100 A2 of solvent accessible surface area. Accepted 2020-MAR-10 by ORCHARD
