C8G Gene (Protein Coding)

Complement C8 Gamma Chain

GC09P136944
GIFtS:
41
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 an... See more...

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 C8 Gamma Chain) is a Protein Coding gene. Diseases associated with C8G include Immunodeficiency Due To A Late Component Of Complement Deficiency and Acute Salpingo-Oophoritis. Among its related pathways are Immune response Lectin induced complement pathway and Creation of C4 and C2 activators. Gene Ontology (GO) annotations related to this gene include complement binding.

UniProtKB/Swiss-Prot Summary 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.
