Gene: IL23A (interleukin 23 subunit alpha) Homo sapiens
Symbol: IL23A
Name: interleukin 23 subunit alpha
Description: Contributes to interleukin-23 receptor binding activity. Involved in several processes, including positive regulation of cytokine production; positive regulation of lymphocyte proliferation; and positive regulation of receptor signaling pathway via JAK-STAT. Localizes to the interleukin-23 complex.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: IL-23; IL-23 subunit alpha; IL-23-A; IL-23A; IL-23p19; IL23P19; interleukin 23 p19 subunit; interleukin 23, alpha subunit p19; interleukin-23 subunit alpha; interleukin-23 subunit p19; interleukin-six, G-CSF related factor; JKA3 induced upon T-cell activation; MGC79388; P19; SGRF
