Protein Structure
UniProt Annotation
Function 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. {ECO:0000269PubMed:11114383, ECO:0000269PubMed:11390512, ECO:0000269PubMed:12610626, ECO:0000269PubMed:12847224, ECO:0000269PubMed:14662908, ECO:0000269PubMed:14978083, ECO:0000269PubMed:16157683, ECO:0000269PubMed:16648837, ECO:0000269PubMed:16670770, ECO:0000269PubMed:16688182}.
