Protein Structure

UniProt Annotation

Function

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. {ECO:0000269PubMed:16828986, ECO:0000269PubMed:18585462}.

Subcellular Localization

Membrane {ECO:0000250}; Single-pass type I membrane protein {ECO:0000250}. Cell junction, synapse {ECO:0000250}. Cell junction, synapse, postsynaptic cell membrane, postsynaptic density {ECO:0000250}. Note=Detected in excitatory, but not inhibitory, synaptic plasma membrane. {ECO:0000250}.

Disease Associations

Tissue Specificity

Predominantly expressed in the brain, with a weak, but broad expression in the cerebral cortex and diencephalic nuclei. Also detected in other parts of the central nervous system, including the olfactory bulb, pons, cerebellum, and medulla oblongata, as well as in the peripheral nervous system, such as the ganglia of cranial nerves and the dorsal root ganglion during gestation. {ECO:0000269PubMed:16828986}.
