Human Complement component 3, C3 (alternative names include acylation-stimulating protein (ASP) C3 is encoded by gene located 19p13.3-p13.2.
Because C3, C4, and C5 are strikingly similar suggesting a common evolutionary origin.
C3 is an acute phase reactant.
Synthesis of C3, a glycoprotein, is induced during acute inflammation.
The liver is the main site of synthesis, although small amounts are also produced by activated monocytes and macrophages.
A single chain precursor (pro-C3) of approximately 200kD is found intracellularly; the cDNA shows that it comprises 1,663aa.
This is processed by proteolytic cleavage into alpha (~115kD) and beta subunits (~75kD) which in the mature protein are linked by disulfide bonds.
