It carries a cytokine-binding homology region, which is divided in two fibronectin type-III (FN-III) domains termed D1 and D2. Each domain contains seven beta-strands that form a sandwich of two antiparallel beta-sheets. The N-terminal D1 domain of IL-2Rbeta includes two highly conserved disulfide bridges [2]. This entry describes D1 of the N-terminal region of IL2Rbeta.

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-distal D1 domain, characterised by a ABED/C'CFG topology stabilized by a disulfide bridge [2]. This domain contains the three regions that grasp TSLP [2].

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].
