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].

It contains two ectodomains with Ig-like topology. This family represents the first of these domains. It also includes domains of interleukin-13 receptor subunit alpha-2 also known as IL-13RA2 that is known to bind with high affinity to interleukin-13.

It forms a functional complex with TSLP and IL7R which is capable of stimulating cell proliferation through activation of STAT3 and STAT5. CRFL2 is implicated in the development of the hematopoietic system [1]. It consists of two FnIII-like domains, D1 and D2. This entry represents the membrane-proximal D2 domain, which displays a an ABE/C'CFG topology with two disulfide bridges [1]. This domain interacts with IL7R D2 domain and forms a compact network of interactions [1]. This domain is also found in the cytokine receptor common subunit gamma (IL2RG), a common subunit for the receptors for a variety of interleukins [2,3].
