  • 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.
  • Post-translational
    C-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.
