Interleukin-23 subunit alpha is a protein that in humans is encoded by the IL23A gene .[ 5] [ 6] The protein is also known as IL-23p19. It is one of the two subunits of the cytokine Interleukin-23.
Interleukin-23 (IL-23) is a heterodimeric cytokine composed of an Interleukin 23 alpha subunit and an IL-12p40 subunit. The IL-12p40 , also known as Interleukin 12 subunit beta , is used by both IL-23 (where it partners with IL-23p19 ) and IL-12 (where it partners with IL-12A ).[ 5] A functional receptor for IL-23 (the IL-23 receptor ) has been identified and is composed of IL-12R β1 and IL-23R .[ 7]
