MIL 33 His Recombinant Protein

Source : Escherichia Coli. IL33 Mouse, His Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 181 amino acids (109-266 a.a) and having a molecular mass of 18.1kDa.IL33 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Interleukin 33 (IL-33) is a 32kDa proinflammatory cytokine that may also regulate gene transcription in producer cells. IL-33 is structurally related to IL-1, which induces helper T cells to produce type 2 cytokines and acts through the receptor IL1RL-1 (IL1 receptor-like-1), which is known also as ST2. Binding of IL-33 to this receptor activates NF-kappa-B and MAP kinases and induces in vitro Th2 cells to produce cytokines. In vivo, IL-33 induces expression of IL-4, IL-5, IL-13 and leads to severe pathological changes in mucosal organs and in vitro, it can be divided to N-terminal fragment of 12kDa and C-terminal fragment of 18kDa by cleavage of caspase-1.
