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:0000256|ARBA:ARBA00002409}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000256|ARBA:ARBA00004613}.
CC -!- SIMILARITY: Belongs to the complement C6/C7/C8/C9 family.
CC {ECO:0000256|ARBA:ARBA00009214}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|PROSITE-ProRule:PRU00124}.
