Activation of the complement system results in formation of the membrane attack complex (MAC) on the membranes of target cells.
The complex is assembled by sequential addition of 1 molecule each of C5b, C6, C7, and C8 and 6 to 16 molecules of the ninth component, C9
DiScipio et al.
(1984) screened a human liver cDNA library by the colony-hybridization technique using 2 radiolabelled oligonucleotide probes that correspond to known regions of the C9 aa sequence.
The cDNA coding for C9 was sequenced and the protein sequence--537aa in a single polypeptide chain-was derived.
The N-terminal half of C9 is predominantly hydrophilic and the C-terminal half is more hydrophobic.
