Product Description

IL-21R (Interleukin 21 receptor), also known as NILR, belongs to the type I cytokine receptor family and Type 4 subfamily. This receptor is Heterodimer with the common gamma subunit and transduces the growth promoting signal of IL21. It is important for the proliferation and differentiation of T cells, B cells, and NK cells. The ligand binding of this receptor leads to the activation of multiple downstream signaling molecules, including JAK1, JAK3, STAT1, and STAT3. B cell IL-21 R engagement induces Blimp-1, and is important for memory responses. It engagement on mouse NK cells enhances their cytotoxic activity and IFN-gamma production. It is selectively expressed in lymphoid tissues and most highly expressed in thymus and spleen and IL21 impacts some cell types, including CD8+ memory T-cells, NK cells, and subsets of CD4 memory T cells. It is also necessary for sufficient numbers of regulatory T cells to combat chronic inflammation. Recombinant mouse IL21R, fused to hIgG-His-Tag at C-terminal, was expressed in HEK293 cell and purified by using conventional chromatography techniques. Source: Recombinant protein corresponding to aa20-237 from mouse IL-21R, fused to hlgG-His-Tag at C-terminal, expressed in HEK293.
