General description

Native, human C3a complement component. Single chain, 77 amino acid peptide. Activation of either complement pathway can result in formation of C3-cleaving enzyme (C3 convertases) on target surfaces. The C3 convertase enzymes of either complement activation pathway will cleave the C3 α-chain at peptide bond 77, resulting in the production and release of the C3a peptide. C3a, one of the three complement-derived anaphylatoxins, expresses a wide variety of biological activities, which include smooth muscle contraction, platelet and neutrophil activation and aggregation, skin wheal and flare, and immunoregulatory reactions.
