[[http://www.uniprot.org/uniprot/CO8A_HUMAN CO8A_HUMAN]] Defects in C8A are a cause of complement component 8 deficiency type 1 (C8D1) [MIM:[http://omim.org/entry/613790 613790]]. A rare defect of the complement classical pathway associated with susceptibility to severe recurrent infections, predominantly by Neisseria gonorrhoeae or Neisseria meningitidis. | |||
==Function== | |||
[[http://www.uniprot.org/uniprot/CO8A_HUMAN CO8A_HUMAN]] 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. C8A inserts into the target membrane, but does not form pores by itself.<ref>PMID:7440581</ref><ref>PMID:17872444</ref> [[http://www.uniprot.org/uniprot/CO8G_HUMAN CO8G_HUMAN]] C8 is a constituent of the membrane attack complex. C8 binds to the C5B-7 complex, forming the C5B-8 complex. C5-B8 binds C9 and acts as a catalyst in the polymerization of C9. The gamma subunit seems to be able to bind retinol. | |||
