Summaries for C8G Gene

Entrez Gene Summary for C8G Gene

  • The protein encoded by this gene belongs to the lipocalin family. It is one of the three subunits that constitutes complement component 8 (C8), which is composed of a disulfide-linked C8 alpha-gamma heterodimer and a non-covalently associated C8 beta chain. C8 participates in the formation of the membrane attack complex (MAC) on bacterial cell membranes. While subunits alpha and beta play a role in complement-mediated bacterial killing, the gamma subunit is not required for the bactericidal activity. [provided by RefSeq, Jul 2011]

GeneCards Summary for C8G Gene

C8G (Complement Component 8, Gamma Polypeptide) is a Protein Coding gene. Diseases associated with C8G include acute salpingitis and salpingo-oophoritis. Among its related pathways are Complement and coagulation cascades and Complement and coagulation cascades. GO annotations related to this gene include protein complex binding and complement binding.

UniProtKB/Swiss-Prot for C8G Gene

  • 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
