A novel cytokine related to IL-2 and IL-15 was recently identified and designated IL-21. 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. IL-21R forms a complex with the common cytokine receptor g chain, gc, and mediates IL-21 signaling. Both IL-21R and the gc 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.

- IL 21R
- IL-21 receptor
FunctionThis is a receptor for interleukin-21.
Tissue specificitySelectively expressed in lymphoid tissues. Most highly expressed in thymus and spleen.
Sequence similaritiesBelongs to the type I cytokine receptor family. Type 4 subfamily.
Contains 2 fibronectin type-III domains.
DomainThe WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding.
The box 1 motif is required for JAK interaction and/or activation.
modificationsC-mannosylated at Trp-214 in the WSXWS motif, the sugar chain makes extensive hydrogen bonds with Asn-73 sugar, and bridges the two fibronectin domains transforming the V-shaped receptor into an A-frame.
