Bind to receptors on the presynaptic terminal

WebThe notion of presynaptic receptors dates from the discovery of presynaptic inhibition, which itself followed the understanding of postsynaptic inhibition and postsynaptic … WebNeurexins are a large family of proteins that act as neuronal cell-surface receptors. The function and localization of the various neurexins, however, have not yet been clarified. Beta-neurexins are candidate receptors for neuroligin-1, a postsynaptic membrane protein that can trigger synapse formation at axon contacts.
