CC   -!- FUNCTION: Cytokine that can act as a growth factor for activated T and
CC       NK cells, enhance the lytic activity of NK/lymphokine-activated killer
CC       cells, and stimulate the production of IFN-gamma by resting PBMC.
CC       {ECO:0000250}.
CC   -!- FUNCTION: Associates with IL23A to form the IL-23 interleukin, a
CC       heterodimeric cytokine which functions in innate and adaptive immunity.
CC       IL-23 may constitute with IL-17 an acute response to infection in
CC       peripheral tissues. IL-23 binds to a heterodimeric receptor complex
CC       composed of IL12RB1 and IL23R, activates the Jak-Stat signaling
CC       cascade, stimulates memory rather than naive T-cells and promotes
CC       production of pro-inflammatory cytokines. IL-23 induces autoimmune
CC       inflammation and thus may be responsible for autoimmune inflammatory
CC       diseases and may be important for tumorigenesis (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Heterodimer with IL12A; disulfide-linked. The heterodimer is
CC       known as interleukin IL-12. Heterodimer with IL23A; disulfide-linked.
CC       The heterodimer is known as interleukin IL-23. Also secreted as a
CC       monomer (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- SIMILARITY: Belongs to the IL-12B family. {ECO:0000305}.
