CO5 Polyclonal Antibody

disease:Defects in C5 are the cause of complement C5 deficiency [MIM:609536]. Patients with dysfunction of C5 display a propensity for severe recurrent infections.,disease: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.,function: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.,function: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).,online information:C5 mutation db,online information:Complement C5 entry,similarity:Contains 1 anaphylatoxin-like domain.,similarity:Contains 1 NTR domain.,subunit:C5 precursor is first processed by the removal of 4 basic residues, forming two chains, beta and alpha, linked by a disulfide bond. C5 convertase activates C5 by cleaving the alpha chain, releasing C5a anaphylatoxin and generating C5b (beta chain + alpha' chain).,
