| UniProt code: P06684. |
| Organism: | Mus musculus (Mouse). | |

| 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. 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. C5a is also a potent chemokine which stimulates the locomotion of polymorphonuclear leukocytes and directs their migration toward sites of inflammation. {ECO:0000250|UniProtKB:P01031}. | |
| 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). The C5a anaphylatoxin interacts with C5AR1. {ECO:0000250|UniProtKB:P01031}. | |
| Subcellular location: | Secreted. | |
| Disease: | Note=Murine C5 deficiency is caused by a 2 base-pairs deletion resulting in frameshift and premature truncation. All C5-deficient strains contain this mutation. {ECO:0000269|PubMed:2303408}. | |
