The neuroligin-neurexin complex is a heterophilic adhesion system at neuronal synapses. Both neuroligins and neurexins have synaptogenic activities that organize pre- and postsynaptic compartments in a bidirectional manner. Multiple genes, alternative promoters, and extensive alternative splicing generate neuroligin and neurexin variants that may underlie synapse-specific functions. In human patients, mutations in neuroligin and neurexin genes are associated with neurodevelopmental disorders, highlighting the importance of these proteins for cognitive function.
