Supplier: AdipoGen AG40B0169C010
IL-38 (aa 20-152) (human) (rec.) (His) (10 µg), AdipoGen Life Sciences. Protein. Human IL-38 (aa Leu20-Trp152) is fused at the C-terminus to a His-tag. Source: E. coli. Endotoxin content: <0.01EU/µg purified protein (LAL test; Lonza). Lyophilized. Contains PBS. Purity: >95% (SDS-PAGE). IL-38 (IL-1F10) belongs to the IL-1 family of proteins. IL-38 is expressed in heart, placenta, fetal liver, spleen, thymus and tonsil. The expression in a variety of immune tissues and similarity to IL-1Ra suggest a role of IL-38 in the inflammatory response. Recently it has been shown that IL-38 is N-terminally processed and secreted by apoptotic cells. Released processed IL-38 (20-152) binds to the receptor Interleukin-1 receptor accessory protein-like 1 (IL1RAPL1; TIGIRR-2) at the surface of macrophages. Processed IL-38-activated IL1RAPL1 reduces the production of IL-6 leading to inflammation attenuation. IL-38 is unregulated during some autoimmune diseases such as Systemic Lupus Erythematosus.
