Neuroligin-3 (NLGN3)

Cell surface protein involved in cell-cell-interactions through its interactions with neurexin family members. Plays a role in synapse function and synaptic signal transmission, and might mediate its effects by clustering other synaptic proteins.

May promote the first formation of synapses, but isn't vital for this. May also play a role in glia-glia or glia-neuron interactions in the developing peripheral nervous system (By similarity).
