Predicted to be involved in several processes, including regulation of neurotransmitter receptor localization to postsynaptic specialization membrane; regulation of presynapse assembly; and synaptic membrane adhesion. Is active in synapse. Is expressed in several structures, including alimentary system; branchial arch; central nervous system; embryo mesenchyme; and sensory organ.
