Involved in regulation of presynapse assembly. Acts upstream of or within several processes, including GABAergic synaptic transmission; positive regulation of synapse assembly; and synapse organization. Located in GABA-ergic synapse and cell surface. Is integral component of postsynaptic membrane. Is expressed in alimentary system; bladder; central nervous system; neural retina; and peripheral nervous system. Orthologous to human SLITRK3 (SLIT and NTRK like family member 3).
