This is the receptor for interleukin-5. The alpha chain binds to IL5.
Expressed on eosinophils and basophils.
Belongs to the type I cytokine receptor family. Type 5 subfamily.
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.
