MeSH definition : A 63-kDa serum glycoprotein encoded by gene C9. Monomeric C9 (mC9) binds the C5b-8
complex to form C5b-9 which catalyzes the polymerization of C9 forming C5b-p9 (MEMBRANE
ATTACK COMPLEX) and transmembrane channels leading to lysis of the target cell. Patients
with C9 deficiency suffer from recurrent bacterial infections.;
