Invitrogen™ Human Complement C5 (aa 1302-1432) Control Fragment Recombinant Protein

C5 (Complement C5) is a Protein Coding gene. Diseases associated with C5 include Complement Component 5 Deficiency and Eculizumab, Poor Response To. Among its related pathways are GPCR downstream signalling and Acquired partial lipodystrophy / Barraquer-Simons syndrome. Gene Ontology (GO) annotations related to this gene include signaling receptor binding and endopeptidase inhibitor activity. An important paralog of this gene is C3. This gene encodes a component of the complement system, a part of the innate immune system that plays an important role in inflammation, host homeostasis, and host defense against pathogens. The encoded preproprotein is proteolytically processed to generate multiple protein products, including the C5 alpha chain, C5 beta chain, C5a anaphylatoxin and C5b. The C5 protein is comprised of the C5 alpha and beta chains, which are linked by a disulfide bridge. Cleavage of the alpha chain by a convertase enzyme results in the formation of the C5a anaphylatoxin, which possesses potent spasmogenic and chemotactic activity, and the C5b macromolecular cleavage product, a subunit of the membrane attack complex (MAC). Mutations in this gene cause complement component 5 deficiency, a disease characterized by recurrent bacterial infections. Alternative splicing results in multiple transcript variants.
