Semaphorin 4B interacts with the post-synaptic density protein PSD-95/SAP90 and is recruited to synapses through a C-terminal PDZ-binding motif

The semaphorins are a large family of proteins that act as guidance signals for axons and dendrites. The class 4 semaphorins are integral membrane proteins that are widely expressed throughout the nervous system. Here, we show that a subclass of these semaphorins is characterized by a PDZ-binding mo...
