Interleukin-1 Family Member 5, human recombinant (rHuIL-1F5)

Human recombinant IL1F5 produced in E.coli is a single, non-glycosylated, polypeptide chain containing 155 amino acids and having a molecular mass of 17kDa. Human interleukin family 1, member 5 (IL-1F5 / FIL1-delta) belongs to the interleukin 1 cytokine family. IL1F5 is expressed by a variety of cells including monocytes, Bcells, dendritic cells/Langerhans cells, keratinocytes,and gastric fundus Parietal and Chief cells. IL1F5 is an antagonist of IL1F9, however IL1F5 activity related to receptor binding remains unclear. Human and mouse IL1F5 share 90% amino acid sequence identity.
