IL-33: Mouse Interleukin-33
Description
BACKGROUND Interleukin 33 (IL-33) is a member of the IL-1 cytokine family and is constitutively expressed in smooth muscle and airway epithelial cells. IL-33 signals through the interleukin 1 receptor-like 1 (IL-1R1) and interleukin-1 receptor accessory protein (IL1RAP) receptors to ativate NF-κB and MAPK signaling pathways. IL-33 functions to induce type 2 cytokine production in polarized Type 2 T helper (Th2) cells.
Recombinant mouse Interleukin 33 is a non-glycosylated protein monomer, containing 159 amino acids and having a molecular mass of 17.7 kDa.
