The Notch pathway is a fundamental signalling system in most multicellular animals. We have determined the X-ray crystal structure of the extracellular domain of the Notch ligand delta-like ligand-1 (Dll-1). The structure incorporates the N-terminal C2 domain, receptor-binding DSL domain and the first six (of eight) EGF (epidermal growth factor)-like repeats, which form a highly extended conformation, confirmed by analytical ultracentrifugation. Comparison of our structure with a fragment of Jagged1 ligand allows us to dissect the similarities and differences between the ligand families. Differences in the C2 domains of Dll-1 and Jagged1 suggest their lipid-binding properties are likely to d..
