CC -!- FUNCTION: Associates with IL12B to form the pro-inflammatory cytokine
CC IL-23 that plays different roles in innate and adaptive immunity
CC (PubMed:11114383). Released by antigen-presenting cells such as
CC dendritic cells or macrophages, binds to a heterodimeric receptor
CC complex composed of IL12RB1 and IL23R to activate JAK2 and TYK2 which
CC then phosphorylate the receptor to form a docking site leading to the
CC phosphorylation of STAT3 and STAT4 (PubMed:32474165, PubMed:29287995,
CC PubMed:33606986). This process leads to activation of several pathways
CC including p38 MAPK or NF-kappa-B and promotes the production of pro-
CC inflammatory cytokines such as interleukin-17A/IL17A (PubMed:12023369).
CC In turn, participates in the early and effective intracellular
CC bacterial clearance (PubMed:32474165). Promotes the expansion and
CC survival of T-helper 17 cells, a CD4-positive helper T-cell subset that
CC produces IL-17, as well as other IL-17-producing cells
CC (PubMed:17676044). {ECO:0000269|PubMed:11114383,

CC ECO:0000269|PubMed:32474165, ECO:0000269|PubMed:33606986}.
CC -!- SUBUNIT: Heterodimer with IL12B; disulfide-linked (PubMed:11114383,
CC PubMed:18680750). The heterodimer is known as interleukin IL-23
CC (PubMed:11114383, PubMed:18680750). Interacts with IL23R; this
CC interaction enables recruitment of IL12RB1 (PubMed:29287995,
CC PubMed:33606986). {ECO:0000269|PubMed:11114383,

CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:11114383}.
CC Note=Secreted upon association with IL12B.
CC -!- TISSUE SPECIFICITY: Secreted by activated dendritic and phagocytic
CC cells and keratinocytes. Also expressed by dermal Langerhans cells (at
CC protein level). {ECO:0000269|PubMed:11114383,
CC ECO:0000269|PubMed:16424222}.
CC -!- DEVELOPMENTAL STAGE: Expressed by newborns dendritic cells.
CC {ECO:0000269|PubMed:16342235}.
CC -!- INDUCTION: Up-regulated by a wide array of pathogens and pathogen-
CC products together with self-signals for danger or injury. Up-regulated
CC in psoriatic dermal tissues, in dendritic cells of multiple sclerosis
CC patients and in tumors. {ECO:0000269|PubMed:12421946,
CC ECO:0000269|PubMed:15114670, ECO:0000269|PubMed:15486065,

CC ECO:0000269|PubMed:16688182, ECO:0000269|PubMed:16751425}.
