Biochem/physiol Actions

C8 beta is one of the three subunits that comprise the component 8 (C8) of the complement system. C8 participates in the formation of Membrane Attack Complex that results in the lysis of cells. Patients with C8B deficiency are prone to bacteria infection.
C8B (C82) is the beta component that makes up the complement component 8 (C8) protein. The other two components are the alpha and the gamma subunits. C8 is one of the components of membrane attack complex that mediates cell lysis and enables the membrane penetration by the complex. C2B mediates the interaction of C8 and C5b-7 components of the membrane attack complex.

Complement component C8 plays a pivotal role in the formation of the membrane attack complex (MAC), an important antibacterial immune effector. C8 initiates membrane penetration and coordinates MAC pore formation. High-resolution structures of C8 subunits have provided some insight into
Leslie L Lovelace et al.

C8 is one of five complement proteins that assemble on bacterial membranes to form the lethal pore-like "membrane attack complex" (MAC) of complement. The MAC consists of one C5b, C6, C7, and C8 and 12-18 molecules of C9. C8 is
