A possible role of these interactions is to recruit postsynaptic adaptor proteins to the site of synaptic junctions. |

Moreover, Neph2 protein is detected in the brain PSD fraction and interacts with PSD-95 in synaptosomal lysates. Functionally, loss of Neph2 in mice leads to age-specific defects in the synaptic connectivity of DG neurons. |

In the present study, we provide evidence that TANC1 and its close relative TANC2 regulate dendritic spines and excitatory synapses. our results indicate that TANC-dependent spine/synapse maintenance requires TANC binding to PSD-95, which promotes synaptic localization of TANC proteins. Thus, it is likely that interaction with PSD-95 concentrates TANC proteins at synapses, where they play a role in mediating PSD-95-dependent maintenance of spines and synapses. |

In vivo Arf pull down assay demonstrated that IQ-ArfGEF/BRAG1 activated Arf6 more potently than Arf1.IQ-ArfGEF/BRAG1 is a guanine nucleotide exchange factor for Arf6 that interacts with PSD-95 at postsynaptic density of excitatory synapses. Taken together, IQ-ArfGEF/BRAG1 forms a postsynaptic protein complex containing PSD-95 and NMDA receptors at excitatory synapses, where it may function as a GEF for Arf6. |

Using Western blotting, we validated our MS approach confirming the binding of Dgl4 (also known as PSD95) and VPS35 to the recombinant Ptchd1 C terminus. Endogenous DLG4 and VPS35 from membrane and soluble mouse brain fractions were recovered specifically on the GST fusion proteins containing the cytoplasmic but not the extracellular, negative control sequences of Ptchd1 (Fig. 5E). Binding of DLG4 was dependent on the PDZ-binding motif in Ptchd1, whereas VPS35 binding was not (Fig. 5E). These results demonstrate a biochemical interaction of Ptchd1 with postsynaptic trafficking proteins in the mouse brain. Together, these data suggest that loss of Ptchd1 results in severe alterations in synaptic function in the dentate gyrus |

Similarly to CASK, PSD95 binds to intracellular adaptor proteins, and especially to GKAP (a protein that binds to the guanylate-kinase domain of PSD95), which, in turn, binds to SHANK proteins (Fig. 1b). |

SAPAPs are specifically expressed in neuronal cells and enriched in the PSD fraction. SAPAPs induce the enrichment of PSD-95/SAP90 to the plasma membrane in transfected cells. Thus, SAPAPs may have a potential activity to maintain the structure of PSD by concentrating its components to the membrane area. |

Like NRXNs, NLGNs bind to intracellular PDZ-domain proteins, but in contrast to NRXNs, NLGNs bind to class I PDZ domains such as those contained in PSD95, a postsynaptic MAGUK protein65. PSD95 and its homologues are centrally involved in recruiting glutamate receptors at postsynaptic sites66. Similarly to CASK, PSD95 binds to intracellular adaptor proteins, and especially to GKAP (a protein that binds to the guanylate-kinase domain of PSD95), which, in turn, binds to SHANK proteins (Fig. 1b). A possible role of these interactions is to recruit postsynaptic adaptor proteins to the site of synaptic junctions. |

Another central component of the NMDA receptor signaling complex is the scaffold protein PSD-95 (also referred to as SAP-90). The first and second PDZ domains bind tightly to the tails of the NR2 subunits of the NMDA receptor |

The PDZ domains of PSD-95 and related proteins interact with the COOH-terminal sequences of K+channels and NMDA2 receptors (3). By these interactions, PSD-95 may mediate the clustering of K+ channels and NMDA receptors at synapses. |

The reversible removal of AIDA-1 from the PSD core under excitatory conditions is similar to the redistribution of another abundant PSD protein, SynGAP. Both SynGAP-alpha1 and AIDA-1 are known to bind PSD-95. |

In the present study, we provide evidence that TANC1 and its close relative TANC2 regulate dendritic spines and excitatory synapses. our results indicate that TANC-dependent spine/synapse maintenance requires TANC binding to PSD-95, which promotes synaptic localization of TANC proteins. Thus, it is likely that interaction with PSD-95 concentrates TANC proteins at synapses, where they play a role in mediating PSD-95-dependent maintenance of spines and synapses. |
