Background: IL-21R

The interleukin-21 (IL-21) and its receptor appear to play important roles in the regulation of the immune system. IL-21 R, also called NILR (novel interleukin receptor) is a type I cytokine receptor with 4 conserved cysteine residues and an extracellular WSXWS motif. It is most closely related to IL-2 R beta and IL-4 R alpha. Mouse IL-21 R is a 529 amino acid (aa) residue protein with a 19 aa signal peptide, a 217 aa extracellular domain, an 18 aa transmembrane domain, and a 275 aa cytoplasmic domain. Mouse and human IL-21 R share 62% aa identity. IL-21 R is expressed on lymphoid tissues, peripheral B cells, and cell lines of T, B and natural killer lineage. Although not fully elucidated, the IL-2 R gamma ( gamma c) chain appears to play a role in IL-21 R signaling. The IL-21/IL-21 R interaction appears to play important roles in B and T cell proliferation after antigen stimulation and natural killer cell maturation.
