part of receptor clustering presynaptic membrane assembly neurexin clustering involved in presynaptic membrane assembly GO:0097115 2011-07-31T05:40:00Z The receptor clustering process involved in assembly of the presynaptic membrane in which neurexins are localized to distinct domains in the cell membrane. Neurexins are synaptic cell surface proteins which act as cell recognition molecules at nerve terminals. Nrxn clustering pr biological_process neurexin clustering presynaptic neurexin clustering
