Technical Data
Interleukin 21 Receptor (IL-21R)
A novel cytokine related to IL2 and IL15 was recently identified and designated IL-21 (1). The receptor for IL-21 (IL-21R, also termed NILR for novel Interleukin receptor) is a new member of the class I cytokine receptor family (1,2). IL-21R forms a complex with the common cytokine receptor gamma chain, gammac, and mediates IL-21 signaling (3,4). Both IL-21R and the gammac are necessary for the IL-21 function. IL-21 and its receptor activate JAK-STAT signaling pathway. IL-21R is expressed in spleen, thymus, natural killer (NK), T and B cell lines. IL-21 plays a role in the proliferation and maturation of NK, B and T cell populations.

Suitable for use in ELISA and Immunohistochemistry. Other applications not tested.
