Background

Non-enzymatic component of C3 and C5 convertases and thus essential for the propagation of the classical complement pathway. Covalently binds to immunoglobulins and immune complexes and enhances the solubilization of immune aggregates and the clearance of IC through CR1 on erythrocytes.

Abbreviation

Complement C4b; C4b

Synonyms

C4; C4b; CO4; Complement C4; Complement C4 beta chain
