摘要：

Neuroligin 3 (NLGN3) and neurexins (NRXNs) constitute a canonical transsynaptic cell-adhesion pair, which has been implicated in autism. In autism spectrum disorder (ASD) development of sociality can be impaired. However, the molecular mechanism underlying NLGN3-mediated social development is unclear. Here, we identify non-canonical interactions between NLGN3 and protein tyrosine phosphatase delta (PTP delta) splice variants, competing with NRXN binding. NLGN3-PTP delta complex structure revealed a splicing-dependent interaction mode and competition mechanism between PTP delta and NRXNs. Mice carrying a NLGN3 mutation that selectively impairs NLGN3-NRXN interaction show increased sociability, whereas mice where the NLGN3-PTP delta interaction is impaired exhibit impaired social behavior and enhanced motor learning, with imbalance in excitatory/inhibitory synaptic protein expressions, as reported in the Nlgn3 R451C autism model. At neuronal level, the autism-related Nlgn3 R451C mutation causes selective impairment in the non-canonical pathway. Our findings suggest that canonical and non-canonical NLGN3 pathways compete and regulate the development of sociality. Mutations of Neuroligin 3 (NLGN3) have been associated with autism spectrum disorder (ASD). Here, the authors identify a previously undescribed interaction between NLGN3 and a splice variant of protein tyrosine phosphatase delta (PTP delta) and its role in development of social behaviour in mice.
