Interleukin-3 (IL-3) is an activated T cell product that bridges innate and adaptive immunity and contributes to several immunopathologies. Structure of IL-3 receptor alpha chain (IL3Ra) in complex with the anti-leukemia antibody CSL362 reveals that the N-terminal domain (NTD), a domain also present in the granulocyte-macrophage colony-stimulating factor (GM-CSF), contains the CSL362 binding epitope. Furthermore, NTD of IL3Ra adopts a typical fibronectin type III (FnIII) fold [1].	Domain
