Preparation and Storage

Background: Complement Component C2

The classical complement pathway plays a major role in innate immunity against infection. This pathway is triggered by C1, a multimolecular complex composed of the recognition protein C1q and two serine proteases, C1r and C1s (1). After activation by C1, the single-chain form of C2 (amino acid residues 21‑752) becomes two chains, which are referred to as C2A and C2B. C2A (residues 244‑752) consists of a vWF domain (residues 254‑452) and a serine protease domain (residues 466‑752). C2B (residues 21‑243) contains 3 Sushi (SCR) domains. C2A, then combines with complement factor 4B to generate the C3 or C5 convertase. The full‑length of human C2 was expressed, and the purified protein corresponded to the single-chain form with the peptidase activity.
