IL-7Ralpha carries a 219 residue ectodomain on the N-terminal region which is crucial for T and B-cell development. Mutations in the IL-7Ralpha ectodomain inhibits T and B cell development, resulting in patients with a form of severe combined immunodeficiency (SCID). The ectodomain folds into two fibronectin type III (FNIII) domains connected by a 310-helical linker. This entry comprises the first of the two FNIII domains, D1 while D2 domain is Pfam:PF00041. In the D1 domain of IL-7Ralpha, a disulfide bond (C22R-C37R) conserved among cytokine receptor class I (CRH I) family members bridges two beta strands [1].

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].

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].
