Ovaj gen kodira p19 podjedinicu heterodimerskog citokina interleukin 23 (IL23). IL23 se sastoji od ovog proteina i p40 podjedinice interleukina 12 (IL12B). IL23 receptor je formiran od beta 1 podjedinice IL12 (IL12RB1) i IL23 specifične podjedinice, IL23R. Oba interleukina, IL23 i IL12, mogu aktivirati traskripcioni aktivator STAT4, i stimulisati produkciju interferona gama (INFG). U kontrastu sa IL12, koje deluje uglavnom na naivnim CD4(+) T ćelijama, IL23 preferentno deluje na memorijske CD4(+) T ćelije.^[2]

IL-23 je važan deo inflamatornog odgovora na infekciju. On podstiče izražavanje matriks metaloproteaza MMP9, povećava angiogenezu i redukuje infiltraciju CD8+ T-ćelija. Nedavno, IL-23 je bio impliciran u razvoj kancerogenih tumora. U kombinaciji sa IL-6 i TGF-β1, IL-23 stimuliše naivne CD4+ T ćelije da se diferenciraju u nove podskupove ćelija koje se zovu Th17 ćelije, koje se razlikuju od klasičnih Th1 i Th2 ćelija. Th17 ćelije proizvode IL-17, proinflamatorni citokin koji pojačava T ćelijsko oformljavanje i stimuliše produkciju proinflamatornih molekula kao što su IL-1, IL-6, TNF-alfa, NOS-2, i hemokine rezultujući u inflamaciji. Nokaut miševi deficitni u bilo p40 ili p19, ili u bilo kojoj podjedinici IL-23 receptora (IL-23R i IL12R-β1) razvijaju manje ozbiljne simptome multiple skleroze i upalne bolesti creva naglašavajući važnost IL-23 u inflamatornom putu.^[5][6]
