详细描述:
Interleukin-21 receptor, also known as IL-21R is a member of the type I cytokine receptors family. IL-21R forms a heterodimeric receptor complex with the common gamma-chain, a receptor subunit which is also shared by the receptors for Interleukin 2, 4, 7, 9, and 15. Furthermore, IL-21 receptor transduces the growth promoting signal of IL-21, and is significant for the proliferation as well as differentiation of T cells, B cells, and natural killer (NK) cells. The
ligand binding of IL-21 receptor leads to the activation of numerous downstream signalin molecules, including JAK1, JAK3, STAT1, as well as STAT3. IL21R produced in Sf9 cells is a single, glycosylated polypeptide chain (20-232 a.a.) fused to an 8
aa His-tag at the C-terminus. It contains a total of 221 amino acids and has a molecular mass of 25.6 kDa. IL-21R shows multiple bands between 28-40 kDa on SDS-PAGE under reducing conditions and has been purified using proprietary chromatographic techniques.
