Interleukin-23 subunit alpha is a protein that in humans is encoded by the IL23A gene. IL-23 is produced by dendritic cells and macrophages. This gene encodes the p19 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.
