C3 is the most abundant protein of the complement system. C3 can be cleaved in two divalent fragments, where C3b is the larger fragment. C3a is the smaller fragment that is released into the surrounding fluids. C3a can bind to receptors on basophils and mast cells triggering them to release their vasoactive amines (e.g. histamine). Because of the role of these biomarkers in anaphylaxis, C3a is called an anaphylatoxin. C3a is one of the most potent constrictors of smooth muscle cells. C3a has been shown to be a multifunctional pro-inflammatory mediator.
