C8G, is one of three polypeptides (along with C8 alpha and C8 beta) that constitutes C8, a component of the complement system. C8 participates in the formation of Membrane Attack Complex (MAC). Patients with deficiency in C8 are vulnerable to certain bacteria infection. C8gamma is a secreted protein that is able to bind retinol and belongs to the lipocalin family and calycin superfamily. It is synthesised in the liver, monocytes and fibroblast and functions to clear pathogens from an infected host.
