[https://www.uniprot.org/uniprot/IL23A_HUMAN IL23A_HUMAN] Associates with IL12B to form the IL-23 interleukin, a heterodimeric cytokine which functions in innate and adaptive immunity. IL-23 may constitute with IL-17 an acute response to infection in peripheral tissues. IL-23 binds to a heterodimeric receptor complex composed of IL12RB1 and IL23R, activates the Jak-Stat signaling cascade, stimulates memory rather than naive T-cells and promotes production of proinflammatory cytokines. IL-23 induces autoimmune inflammation and thus may be responsible for autoimmune inflammatory diseases and may be important for tumorigenesis.<ref>PMID:11114383</ref> <ref>PMID:12023369</ref> <ref>PMID:16424222</ref>

== Publication Abstract from PubMed ==

Interleukin (IL)-23 is a pro-inflammatory cytokine playing a key role in the pathogenesis of several autoimmune and inflammatory diseases. We have determined the crystal structures of the heterodimeric p19-p40 IL-23 and its complex with the Fab (antigen-binding fragment) of a neutralizing antibody at 2.9 and 1.9 A, respectively. The IL-23 structure closely resembles that of IL-12. They share the common p40 subunit, and IL-23 p19 overlaps well with IL-12 p35. Along the hydrophilic heterodimeric interface, fewer charged residues are involved for IL-23 compared with IL-12. The binding site of the Fab is located exclusively on the p19 subunit, and comparison with published cytokine-receptor structures suggests that it overlaps with the IL-23 receptor binding site.
