Complement component C8, B chain

The C8B gene encodes the beta subunit of the complement component 8. C8 participates in the formation of the membrane attack complex (MAC) which disrupts bacterial walls, which mediates cell lysis. Mutations cause autosomal recessive complement C8 deficiency type 2.
