The Notch receptor and its ligands are key components in a core metazoan signalling pathway which regulates the spatial patterning, timing and outcome of many cell-fate decisions. Ligands contain a disulphide-rich Delta/Serrate/LAG-2 (DSL) domain required for Notch trans-activation or cis-inhibition. Here we report the first X-ray structure of a functional fragment of a Notch ligand, the DSL-EGF3 domains of human Jagged-1 (J-1DSL-EGF3). The structure identifies a highly conserved face of the DSL domain and we show, by functional analysis of Drosophila ligand mutants, that this surface is required for both cis- and trans-regulatory interactions with Notch. We also identify, using NMR, a surface of Notch-1 involved in J-1DSL-EGF3 binding. Our data imply that cis- and trans-regulation may occur through formation of structurally distinct complexes which, unexpectedly, involve the same surfaces on both ligand and receptor.
