Although the receptor tyrosine phosphatase LAR is known to regulate the devolvement of excitatory synapse and to direct proper guidance of axons, the extracellular ligand for its activation has remained unknown. This study identifies postsynaptic netrin G-ligand 3 (NGL-3) as the trans-synaptic adhesion ligand of LAR and demonstrates a bidirectional regulation of excitatory synapse formation by the LAR/NGL-3 interaction.
