Anti-Mouse IL-1 R1, Type 1-Biotin (I-434-500ug)

IL-1 binds two receptors, IL-1RI and IL-1RII. The ligands IL-1α and IL-1ß exert all of their various biological actions by binding IL-1RI. IL-1RII has a shortened cytoplasmic domain that is unable to transduce signals and therefore acts as a decoy receptor and competitively antagonizes the binding of IL-1α and IL-1ß, thereby reducing their biological effects. Binding of the ligands to IL-1RI is enhanced by an accessory protein, IL-1R-AcP. IL-1RI is expressed on T cells, thymocytes, dendritic cells, fibroblasts, vascular endothelial cells, epithelial cells and neural cells. It is an 80 kD transmembrane glycoprotein.
