CRLF2 is a receptor for thymic stromal lymphopoietin (TSLP). 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].	Domain

CRLF2 is a receptor for thymic stromal lymphopoietin (TSLP). 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].	Domain
