Application Abreviews Notes
  • Application notesWB: Use at a concentration of 1 µg/ml. Detects a band of approximately 74 kDa (predicted molecular weight: 63 kDa).
    Not yet tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • FunctionConstituent 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 specificityPlasma.
    • Involvement in diseaseDefects 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 similaritiesBelongs 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
      Thrombin cleaves factor C9 to produce C9a and C9b.
      Phosphorylation sites are present in the extracelllular medium.
    • Cellular localizationSecreted. 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.
