      Background InformationInterleukin-23 subunit alpha (IL-23A or IL-23, p19 subunit) is a subunit of heterodimeric cytokine IL-23, which also contains the p40 subunit of interleukin 12 (IL-12B). The receptor of IL-23 is formed by the beta 1 subunit of IL-12 (IL-12RB1) and an IL-23 specific subunit, IL-23R. IL-23 activates the transcription activator STAT4, and stimulates the production of interferon-gamma. IL-23 is an important part of the inflammatory response against infection. It promotes upregulation of the matrix metalloprotease MMP9, increases angiogenesis and reduces CD8+ T-cell infiltration. Recently, IL-23 has been implicated in the development of cancerous tumors. In conjunction with IL-6 and TGF-β1, IL-23 stimulates naive CD4+ T cells to differentiate into a novel subset of cells called Th17 cells, which are distinct from the classical Th1 and Th2 cells. Th17 cells produce IL-17, a proinflammatory cytokine that enhances T cell priming and stimulates the production of proinflammatory molecules such as IL-1, IL-6, TNF-alpha, NOS-2, and chemokines resulting in inflammation.

      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a subunit of the heterodimeric cytokine interleukin 23 (IL23). IL23 is composed of this protein and the p40 subunit of interleukin 12 IL12B). The receptor of IL23 is formed by the beta 1 subunit of IL12 (IL12RB1) and an IL23 specific subunit, IL23R. Both IL23 and IL12 can activate the transcription activator STAT4, and stimulate the production of interferon-gamma (IFNG). In contrast to IL12, which acts mainly on naive CD4(+) T cells, IL23 preferentially acts on memory CD4(+) T cells. [provided by RefSeq].

      UniProt Number
      UniProt SummaryFUNCTION: Associates with IL12B to form the IL-23 interleukin, an 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 an 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.

      SUBUNIT STRUCTURE: Heterodimer with IL12B; disulfide-linked. The heterodimer is known as interleukin IL-23.

      SUBCELLULAR LOCATION: Secreted. Note: Secreted upon association with IL12B.

      TISSUE SPECIFICTY: Secreted by activated dendritic and phagocytic cells and keratinocytes. Also expressed by dermal Langerhans cells (at protein level).

      DEVELOPMENTAL STAGE: Expressed by newborns dendritic cells.

      INDUCTION: Up-regulated by a wide array of pathogens and pathogen-products together with self-signals for danger or injury. Up-regulated in psoriatic dermal tissues, in dendritic cells of multiple sclerosis patients and in tumors.

      SEQUENCE SIMILARITIES: Belongs to the IL-6 superfamily.
      Molecular WeightUniProtKB/Swiss-Prot entry Q9NPF7 lists a molecular weight of 20.730 kDa. In some lysates tested, non-specific bands are observed at around 40 kDa and around 55 kDa.
