CC -!- FUNCTION: Constituent of the membrane attack complex (MAC) that plays a
CC key role in the innate and adaptive immune response by forming pores in
CC the plasma membrane of target cells. {ECO:0000250}.
CC -!- SUBUNIT: Component of the membrane attack complex (MAC). MAC assembly
CC is initiated by proteolytic cleavage of C5 into C5a and C5b. C5b binds
CC sequentially C6, C7, C8 and 12-14 copies of the pore-forming subunit C9
CC (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- PTM: All cysteine residues are assumed to be cross-linked to one
CC another. Individual modules containing an even number of conserved
CC cysteine residues are supposed to have disulfide linkages only within
CC the same module (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the complement C6/C7/C8/C9 family.
CC {ECO:0000305}.
