Neurexins are essential presynaptic cell-adhesion molecules that are linked to schizophrenia and autism, and are subject to extensive alternative splicing. Here, we used a novel genetic approach to test the physiological significance of neurexin alternative splicing. We generated knock-in mice in which alternatively spliced sequence #4 (SS4) of neurexin-3 is constitutively included, but can be selectively excised by cre-recombination. SS4 of neurexin-3 was chosen because it is highly regulated and controls neurexin-binding to neuroligins, LRRTMs, and other ligands. Unexpectedly, constitutive inclusion of SS4 in presynaptic neurexin-3 decreased postsynaptic AMPA- but not NMDA-receptor levels and enhanced postsynaptic AMPA-receptor endocytosis. Moreover, constitutive inclusion of SS4 in presynaptic neurexin-3 abrogated postsynaptic AMPA-receptor recruitment during NMDA-receptor-dependent LTP. These phenotypes were fully rescued by constitutive excision of SS4 in neurexin-3. Thus, alternative splicing of presynaptic neurexin-3 controls postsynaptic AMPA-receptor trafficking, revealing an unanticipated alternative splicing mechanism for trans-synaptic regulation of synaptic strength and long-term plasticity.
