Background	Human Interleukin-31 (IL-31) is a 24 kDa, short-chain member of the alpha -helical family of cytokines. The human IL-31 cDNA encodes a 164 amino acid (aa) precursor that contains a 23 aa signal peptide and a 141 aa mature protein. The mature region shows four alpha -helices which would be expected to show a typical up up down down topology. Human and mouse IL-31 share 24% aa sequence identity in the mature region. IL-31 is mainly associated with activated T cells and preferentially expressed by Th2 rather than Th1 cells. The IL-31 receptor is constitutively expressed by keratinocytes and up regulated by IFN-gamma on monocytes. Studies using transgenic mice indicate that IL-31 may contribute to the pruritis (itching) associated with nonatopic dermatitis.
Gene Symbol	IL31
