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:12023369, ECO:0000269PubMed:16424222}.
Subcellular Localization Secreted {ECO:0000269PubMed:11114383}. Note=Secreted upon association with IL12B.
Disease Associations
Tissue Specificity Secreted by activated dendritic and phagocytic cells and keratinocytes. Also expressed by dermal Langerhans cells (at protein level). {ECO:0000269PubMed:11114383, ECO:0000269PubMed:16424222}.
