Target

  • Function

    Constituent of the membrane attack complex (MAC) that plays a key role in the innate and adaptive immune response by forming pores in the plasma membrane of target cells. C9 is the pore-forming subunit of the MAC.

  • Tissue specificity

    Plasma.

  • Involvement in disease

    Defects in C9 are a cause of complement component 9 deficiency (C9D) [MIM:613825]. A rare defect of the complement classical pathway associated with susceptibility to severe recurrent infections, predominantly by Neisseria gonorrhoeae or Neisseria meningitidis.

  • Sequence similarities

    Belongs to the complement C6/C7/C8/C9 family.
    Contains 1 EGF-like domain.
    Contains 1 LDL-receptor class A domain.
    Contains 1 MACPF domain.
    Contains 1 TSP type-1 domain.

  • Post-translational
    modifications

    Thrombin cleaves factor C9 to produce C9a and C9b.
    Phosphorylation sites are present in the extracelllular medium.

  • Cellular localization

    Secreted. Cell membrane. Secreted as soluble monomer. Oligomerizes at target membranes, forming a pre-pore. A conformation change then leads to the formation of a 100 Angstrom diameter pore.

      Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human colon tissue sections labeling Complement C9 with purified ab173302 at 1/10,000 dilution (0.07 µg/ml). Heat mediated antigen retrieval was performed using ab93684 (Tris/EDTA buffer, pH 9.0). ImmunoHistoProbe one step HRP Polymer (ready to use) was used as the secondary antibody. Negative control: PBS instead of the primary antibody. Hematoxylin was used as a counterstain.
