== Function ==
[https://www.uniprot.org/uniprot/IL7RA_MOUSE IL7RA_MOUSE] Receptor for interleukin-7. Also acts as a receptor for thymic stromal lymphopoietin (TSLP).

== Publication Abstract from PubMed ==
Thymic stromal lymphopoietin (TSLP), a cytokine produced by epithelial cells at barrier surfaces, is pivotal for the development of widespread chronic inflammatory disorders such as asthma and atopic dermatitis. The structure of the mouse TSLP-mediated signaling complex reveals how TSLP establishes extensive interfaces with its cognate receptor (TSLPR) and the shared interleukin 7 receptor alpha-chain (IL-7Ralpha) to evoke membrane-proximal receptor-receptor contacts poised for intracellular signaling. Binding of TSLP to TSLPR is a mechanistic prerequisite for recruitment of IL-7Ralpha to the high-affinity ternary complex, which we propose is coupled to a structural switch in TSLP at the crossroads of the cytokine-receptor interfaces. Functional interrogation of TSLP-receptor interfaces points to putative interaction hotspots that could be exploited for antagonist design. Finally, we derive the structural rationale for the functional duality of IL-7Ralpha and establish a consensus for the geometry of ternary complexes mediated by interleukin 2 (IL-2)-family cytokines.
