IL-23 alpha (175a.a) & IL-12 beta (313a.a) Heterodimer Protein, Mouse (HEK293, His)

IL-23 alpha, a crucial component, combines with IL12B to create the IL-23 interleukin, a heterodimeric cytokine pivotal in innate and adaptive immunity. Operating in peripheral tissues, IL-23, along with IL-17, responds acutely to infections. It binds to IL12RB1 and IL23R, activating Jak-Stat signaling, preferentially stimulating memory T-cells, and inducing pro-inflammatory cytokines. Released by antigen-presenting cells, IL-23 plays a role in autoimmune inflammation, contributing to autoimmune diseases and tumorigenesis, and supports the expansion of T-helper 17 cells. IL-23 alpha (175a.a) & IL-12 beta (313a.a) Heterodimer Protein, Mouse (HEK293, His) is a recombinant protein dimer complex containing mouse-derived IL-23 alpha, expressed by HEK293, with C-His labeled tag. IL-23 alpha (175a.a) & IL-12 beta (313a.a) Heterodimer Protein, Mouse (HEK293, His), has molecular weight of ~47 & 45 & 26 kDa, respectively.

IL-23 alpha, as a crucial component, associates with IL12B to form the IL-23 interleukin, a heterodimeric cytokine playing key roles in both innate and adaptive immunity. Operating in peripheral tissues, IL-23, in conjunction with IL-17, constitutes an acute response to infections. It binds to a heterodimeric receptor complex composed of IL12RB1 and IL23R, activating the Jak-Stat signaling cascade, preferentially stimulating memory T-cells, and fostering the production of pro-inflammatory cytokines. This cytokine induces autoimmune inflammation, potentially contributing to autoimmune inflammatory diseases and playing a significant role in tumorigenesis. Released by antigen-presenting cells such as dendritic cells or macrophages, IL-23 binds to its receptor complex, initiating signaling pathways that activate various cellular responses, including the production of interleukin-17A/IL17A and promoting early and effective intracellular bacterial clearance. Additionally, IL-23 supports the expansion and survival of T-helper 17 cells, a CD4-positive helper T-cell subset known for producing IL-17, along with other IL-17-producing cells.
