A postsynaptic terminal is the receiving part of the connection (synapse) between two nerve cells (neurons). The postsynaptic terminal membrane is less than 50 nanometers away and contains specialized receptors.
Neuroligins (NLs) are postsynaptic cell-adhesion molecules essential for normal synapse function. 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. Neuroligins also affect the properties of neural networks by specifying synaptic functions, and they mediate signalling by recruiting and stabilizing key synaptic components. Neuroligins interact with other postsynaptic proteins to localize neurotransmitter receptors and channels in the postsynaptic density as the cell matures. Neuroligin 1 localizes at excitatory synapses, neuroligin 2 at inhibitory synapses and neuroligin 3 at both. Reduction in the levels of neuroligins 1, 2 and 3 results in a strong reduction of inhibitory input but little reduction in excitatory input. Neuroligin 1 is a synaptic cell-adhesion molecule that is enriched in postsynaptic densities where it may recruit receptors, channels, and signal-transduction molecules to synaptic sites of cell adhesion.
