Application Abreviews Notes
WB 1/500 - 1/1000. Predicted molecular weight: 47 kDa.
IHC-P 1/50 - 1/100.
ICC/IF 1/500 - 1/1000.

  • Function

    Binds with low affinity to interleukin-13 (IL13). Together with IL4RA can form a functional receptor for IL13. Also serves as an alternate accessory protein to the common cytokine receptor gamma chain for interleukin-4 (IL4) signaling, but cannot replace the function of IL2RG in allowing enhanced interleukin-2 (IL2) binding activity.
  • Tissue specificity

    Ubiquitous. Highest levels in heart, liver, skeletal muscle and ovary; lowest levels in brain, lung and kidney. Also found in B-cells, T-cells and endothelial cells.
  • Sequence similarities

    Belongs to the type I cytokine receptor family. Type 5 subfamily.
  • Domain

    The 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.
