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 |

SALMs 1-3 contain a C-terminal PDZ-binding motif, which interacts with PSD-95, an abundant postsynaptic scaffolding protein, whereas SALM4 and SALM5 lack PDZ binding. Interactions between SALMs 1–3 and PSD-95 family proteinscould serve a number of functions. SALM1 and SALM2, which lack the ability to interact with a presynaptic ligand and thus cannot be directly targeted to sites of early synaptic adhesion, may require PSD-95 binding for their localization to early synapses. |

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. |

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. |

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. |

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. |

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. |

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. |

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 |

SALMs 1-3 contain a C-terminal PDZ-binding motif, which interacts with PSD-95, an abundant postsynaptic scaffolding protein, whereas SALM4 and SALM5 lack PDZ binding. Interactions between SALMs 1–3 and PSD-95 family proteinscould serve a number of functions. SALM1 and SALM2, which lack the ability to interact with a presynaptic ligand and thus cannot be directly targeted to sites of early synaptic adhesion, may require PSD-95 binding for their localization to early synapses. |

These results point toward a novel mechanism by which FUS targets neuronal mRNA and given that these PSD-95 and Shank1 3'-UTR G quadruplex structures are also targeted by the fragile X mental retardation protein (FMRP), they raise the possibility that FUS and FMRP might work together to regulate the translation of these neuronal mRNA targets.|As seen in Figure 7 (top panel), both PSD-95 Q1-Q2 and Shank1a GQ probes pulled down endogenous FUS, whereas their M2 mutants did not, indicating that the GQ structure is sufficient for recognition. |

A possible function for the NGL–PSD-95 interaction is to couple trans-synaptic adhesion events to the recruitment of PSD-95 and other PSD-95-associated postsynaptic proteins. PSD-95 and liprin-α may be key synaptic scaffolding proteins that couple trans-synaptic adhesions to the assembly of synaptic proteins/vesicles |

The Scribble polarity complex or module is one of the three polarity modules that regulate cell polarity in multiple epithelia including blood-tissue barriers. This protein complex is composed of Scribble, Lethal giant larvae (Lgl) and Discs large (Dlg), which are well conserved across species from fruitflies and worms to mammals. |

PKCepsilon directly phosphorylated PSD-95 and JNK1 in vitro Inhibiting PKCepsilon, JNK, or calcium/calmodulin dependent kinase II activity prevented the effects of PKCepsilon activators on PSD-95 phosphorylation.|These results indicate that PKCepsilon promotes synaptogenesis by activating PSD-95 phosphorylation directly through JNK1 and calcium/calmodulin dependent kinase II and also by inducing expression of PSD-95 and synaptophysin. |
