Neuroligin 1 is dynamically exchanged at postsynaptic sites.

Neuroligins are postsynaptic cell adhesion molecules that associate with presynaptic neurexins. Both factors form a transsynaptic connection, mediate signaling across the synapse, specify synaptic functions, and play a role in synapse formation. Neuroligin dysfunction impairs synaptic transmission, disrupts neuronal networks, and is thought to participate in cognitive diseases. Here we report t...

Neurexins Induce Differentiation of GABA and Glutamate Postsynaptic Specializations via Neuroligins

Formation of synaptic connections requires alignment of neurotransmitter receptors on postsynaptic dendrites opposite matching transmitter release sites on presynaptic axons. beta-neurexins and neuroligins form a trans-synaptic link at glutamate synapses. We show here that neurexin alone is sufficient to induce glutamate postsynaptic differentiation in contacting dendrites. Surprisingly, neurex...

C. elegans Punctin Clusters GABAA Receptors via Neuroligin Binding and UNC-40/DCC Recruitment

Positioning type A GABA receptors (GABA(A)Rs) in front of GABA release sites sets the strength of inhibitory synapses. The evolutionarily conserved Ce-Punctin/MADD-4 is an anterograde synaptic organizer that specifies GABAergic versus cholinergic identity of postsynaptic domains at the C. elegans neuromuscular junctions (NMJs). Here we show that the Ce-Punctin secreted by GABAergic motor neuron...

Neuroligin 2 Drives Postsynaptic Assembly at Perisomatic Inhibitory Synapses through Gephyrin and Collybistin

In the mammalian CNS, each neuron typically receives thousands of synaptic inputs from diverse classes of neurons. Synaptic transmission to the postsynaptic neuron relies on localized and transmitter-specific differentiation of the plasma membrane with postsynaptic receptor, scaffolding, and adhesion proteins accumulating in precise apposition to presynaptic sites of transmitter release. We ide...

Neuroligin 2 Is Expressed in Synapses Established by Cholinergic Cells in the Mouse Brain

Neuroligin 2 is a postsynaptic protein that plays a critical role in the maturation and proper function of GABAergic synapses. Previous studies demonstrated that deletion of neuroligin 2 impaired GABAergic synaptic transmission, whereas its overexpression caused increased inhibition, which suggest that its presence strongly influences synaptic function. Interestingly, the overexpressing transge...
