生化机理
Interleukin 12 (IL-12) is the founding member of the IL-12 family of heterodimeric cytokines, which have important immunological functions. It is a disulfide-linked, 70 kDa (p70) heterodimeric glycoprotein composed of a 40 kDa (p40) subunit and a 35 kDa (p35) subunit. Mouse IL-12p40 is a 40 kDa glycoprotein that shows considerable structural similarity to the extracellular domain of hematopoietin receptors. It is synthesized as a 335 amino acid (aa) precursor with a 22 aa signal sequence and a 313 aa mature region that contains a 92 aa fibronectin type III domain and an 84 aa Ig C2-like region and has a high degree of structural homology to type I cytokine receptors. There are two intrachain disulfide bonds and four potential N-linked glycosylation sites. Once made, it can exist in multiple forms including monomer, homodimer, heterodimer linked to p19 (forming IL-23), and heterodimer linked to p35 (forming IL-12). Mature mouse IL-12p40 shows 93% and 67% aa sequence identity to rat and human IL-12p40 respectively. The secreted form of the p40 subunit inhibits IL-23 functions and abrogates IL-23-mediated anti-tumor effects. Characterization of the IL-12p40 proteins for binding and bioactivity showed that both the p40 monomer and dimer inhibited IL-12 binding to IL-12R.
