Members of this family are related in overall topology to fibronectin type III modules and fold into a sandwich comprising seven antiparallel beta sheets arranged in a three-strand and a four-strand beta-pleated sheet. They are required for binding of interleukin-4 to the receptor alpha chain, which is a crucial event for the generation of a Th2-dominated early immune response [1].	Domain

This is the N-terminal Ig-like domain found in IL-13Ralpha1 type two cytokine complex. The IL-13Ralpha1 contains an extra N-terminal Ig-like domain not found in other receptors of the the common gamma-chain subfamily. The extra N-terminal IL-13Ralpha1 Ig-like domain contacts the dorsal surfaces of both IL-4 and IL-13. Mutational studies show that the deletion of this domain affects the binding of IL-13 to IL-13Ralpha1 [1].	Domain

They are required for binding to the cytokine Interleukin-6 [1].	Domain
