General Information of Binding Target of SBP (BTS) (ID: ST00006)
BTS Name
Interleukin-23 subunit alpha
Synonyms
IL-23 subunit alpha; IL-23-A; Interleukin-23 subunit p19; IL-23p19
BTS Type
Protein
Family
IL-6 superfamily
Gene Name
IL23A
Organism
Homo sapiens (Human)
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.
