Function

Cell surface protein involved in cell-cell-interactions via its interactions with neurexin family members. Plays a role in synapse function and synaptic signal transmission, and probably mediates its effects by recruiting and clustering other synaptic proteins. May promote the initial formation of synapses, but is not essential for this. In vitro, triggers the de novo formation of presynaptic structures. May be involved in specification of excitatory synapses. {ECO:0000269PubMed:10892652, ECO:0000269PubMed:15620359, ECO:0000269PubMed:16982420}.

Subcellular Localization

Cell 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=Enriched in synaptic plasma membranes and clustered in synaptic clefts and postsynaptic densities. Detected at dendritic spines. Colocalized with DLG4/PSD-95 and GRIN1/NMDAR1 (By similarity). {ECO:0000250}.
