Neuroligin (NLGN), a type I membrane protein, is a cell adhesion protein on the postsynaptic membrane that mediates the formation and maintenance of synapses between neurons.Neuroligins act as ligands for β-Neurexins, which are cell adhesion proteins located presynaptically.Neuroligin and β-neurexin "shake hands", resulting in the connection between two neurons and the production of a synapse. (2011). Cell 141:1068 . McClelland, AC . Recent evidence highlights the importance of a trans-synaptic interaction between postsynaptic neuroligins and presynaptic neurexins. Neuroligins are part of a family of neuronal cell surface proteins that "connect presynaptic and postsynaptic neurons at synapses, mediate signaling across the synapse, and shape the properties of neural networks by specifying synaptic functions".

Affected individuals exhibit qualitative impairment in social interaction, as manifest by impairment in the use of non-verbal behaviors such as eye-to-eye gaze, facial expression, body postures, and gestures, failure to develop appropriate peer relationships, and lack of social sharing or reciprocity. Synaptic damage is a critical hallmark of Alzheimer's disease, and the best correlate with cognitive impairment ante mortem. In these networks, synapses not only transmit signals but also transform and refine them. Given the presumptive synaptic functions of neurexins and CL1, this attractive possibility would imply a trans-synaptic interaction. Nature 455:903-911. 15. .
