IL-38 (IL-1F10) belongs to the IL-1 family. IL-38 is expressed in the fetal skin, spleen and tonsil, generally in the basal epithelia of skin and in proliferating B cells of the tonsil. IL-38 binds soluble IL-1 receptor type 1 and may be implicated in the regulation of adapted and innate immune responses.

Human IL-38 (aa 1-152) is fused at the C-terminus to a His-tag.
