متن کاملLRRTMs and neuroligins bind neurexins with a differential code to cooperate in glutamate synapse development.
Leucine-rich repeat transmembrane neuronal proteins (LRRTMs) were recently found to instruct presynaptic and mediate postsynaptic glutamatergic differentiation. In a candidate screen, here we identify neurexin-1beta lacking an insert at splice site 4 (-S4) as a ligand for LRRTM2. Neurexins bind LRRTM2 with a similar affinity but distinct code from the code for binding neuroligin-1 (the predomin...
متن کاملNeurexins 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...
متن کاملNeurexin-neuroligin signaling in synapse development.
Neurexins and neuroligins are emerging as central organizing molecules for excitatory glutamatergic and inhibitory GABAergic synapses in mammalian brain. They function as cell adhesion molecules, bridging the synaptic cleft. Remarkably, each partner can trigger formation of a hemisynapse: neuroligins trigger presynaptic differentiation and neurexins trigger postsynaptic differentiation. Recent ...
متن کاملNeuroligins Determine Synapse Maturation and Function
Synaptogenesis, the generation and maturation of functional synapses between nerve cells, is an essential step in the development of neuronal networks in the brain. It is thought to be triggered by members of the neuroligin family of postsynaptic cell adhesion proteins, which may form transsynaptic contacts with presynaptic alpha- and beta-neurexins and have been implicated in the etiology of a...
