詳細

Biochem/physiol Actions

Complement C4b fragment is formed by the cleavage of the C4 α-chain by activated C1 enzyme. Like C3b, C4b has the transient ability to form a covalent ester bond with a variety of target cell surfaces. Target surface-bound C4b acts as an important non-enzymatic subunit of the classical pathway C3 cleaving enzyme (C4b, C2a). This surface-bound C4b also exhibits opsonic and immune adherence activities which are dependent on the CR1 (CD35) complement receptor found on many inflammatory cells.
