Abstract Background The vast number of precise intercellular connections within vertebrate nervous systems is only partly explained by the comparatively few known extracellular guidance cues. Large families of neural orphan receptor proteins have been identified and are likely to contribute to these recognition processes but due to the technical difficulty in identifying novel extracellular interactions of membrane-embedded proteins their ligands remain unknown. Results To identify novel neural recognition signals we performed a large systematic protein interaction screen using an assay capable of detecting low affinity extracellular protein interactions between the ectodomains of 150 zebrafish receptor proteins containing leucine-rich-repeat and or immunoglobulin superfamily domains. We screened 7 592 interactions to construct a network of 34 cell surface receptor-ligand pairs that included orphan .
