C3 plays a central role in the activation of the complement system. Its processing by C3 convertase is the central reaction in both classical and alternative complement pathways. After activation C3b can bind covalently, via its reactive thioester, to cell surface carbohydrates or immune aggregates. Derived from proteolytic degradation of complement C3, C3a anaphylatoxin is a mediator of local inflammatory process. In chronic inflammation, acts as a chemoattractant for neutrophils (By similarity). It induces the contraction of smooth muscle, increases vascular permeability and causes histamine release from mast cells and basophilic leukocytes. [C3-beta-c]: Acts as a chemoattractant for neutrophils in chronic inflammation. [Acylation stimulating protein]: adipogenic hormone that stimulates triglyceride (TG) synthesis and glucose transport in adipocytes, regulating fat storage and playing a role in postprandial TG clearance. Appears to stimulate TG synthesis via activation of the PLC, MAPK and AKT signaling pathways. Ligand for C5AR2. Promotes the phosphorylation, ARRB2-mediated internalization and recycling of C5AR2 (PubMed: 8376604, PubMed: 2909530, PubMed: 9059512, PubMed: 10432298, PubMed: 15833747, PubMed: 16333141, PubMed: 19615750).

C3 (complement C3) is the central complement precursor cleaved into C3a and C3b, linking complement activation to inflammatory signalling, opsonization and downstream C5 activation.
Biological function: Complement C3 is activated by C3 convertases across the classical, lectin and alternative pathways. Cleavage generates C3a, an anaphylatoxin involved in inflammatory signalling, and C3b, which covalently labels surfaces for opsonization, supports complement amplification and contributes to C5 convertase formation. Additional processing generates iC3b and other fragments with distinct immune functions.
