C8 is a glycoprotein composed of three nonidentical subunits (C8α, C8β, and C8γ) that are encoded by three separate genes. C8α and C8β are members of the membrane attack complex (MAC) family of structurally related proteins. In contrast, C8γ is unrelated and is a member of the lipocalin family of widely distributed proteins that bind and transport small lipophilic ligands. Learn more, https://www.creative-biola...
