IL-23 alpha (170a.a) & IL-12 beta (306a.a) Heterodimer Protein, Human (Biotinylated, HEK293, His-Avi)

IL-23, collaborating with IL12B, constitutes the pro-inflammatory cytokine IL-23, crucial in innate and adaptive immunity. Released by antigen-presenting cells like dendritic cells or macrophages, IL-23 binds to IL12RB1 and IL23R, activating JAK2 and TYK2. This cascade phosphorylates STAT3 and STAT4, activating pathways like p38 MAPK or NF-kappa-B, inducing pro-inflammatory cytokines. IL-23 contributes to intracellular bacterial clearance and supports the expansion of T-helper 17 cells, including IL-17 producers. The disulfide-linked IL-23 interacts with IL12B and IL23R, recruiting IL12RB1. IL-23 alpha (170a.a) & IL-12 beta (306a.a) Heterodimer Protein, Human (Biotinylated, HEK293, His-Avi) is a recombinant protein dimer complex containing human-derived IL-23 alpha, expressed by HEK293, with C-Avi, C-His labeled tag. IL-23 alpha (170a.a) & IL-12 beta (306a.a) Heterodimer Protein, Human (Biotinylated, HEK293, His-Avi), has molecular weight of 24 kDa (IL-23 alpha) & 40-50 kDa (IL-12 beta), respectively.

IL-23, in collaboration with IL12B, forms the pro-inflammatory cytokine IL-23, playing diverse roles in both innate and adaptive immunity. Released by antigen-presenting cells such as dendritic cells or macrophages, IL-23 binds to a heterodimeric receptor complex comprising IL12RB1 and IL23R, initiating a cascade involving JAK2 and TYK2 activation. These kinases phosphorylate the receptor, creating a docking site for the subsequent phosphorylation of STAT3 and STAT4. This process activates multiple pathways, including p38 MAPK or NF-kappa-B, fostering the production of pro-inflammatory cytokines, such as interleukin-17A/IL17A. Additionally, IL-23 actively participates in the early and effective clearance of intracellular bacteria. Notably, IL-23 promotes the expansion and survival of T-helper 17 cells, a CD4-positive helper T-cell subset known for producing IL-17, alongside other IL-17-producing cells. The heterodimeric association of IL-23 with IL12B, known as interleukin IL-23, is disulfide-linked. Furthermore, IL-23 interacts with IL23R, facilitating the recruitment of IL12RB1.
