Promotes neurite outgrowth in hippocampal neurons. Involved in the regulation and maintenance of excitatory synapses. Induces the clustering of excitatory postsynaptic proteins, including DLG4, DLGAP1, GRIA1 and GRIN1 (By similarity).
Subcellular locations: Membrane, Synapse, Postsynaptic density membrane
Detected in excitatory, but not inhibitory, synaptic plasma membrane.
