Abstract: Disclosed is a polypeptide containing an extracellular domain of a synaptogenic protein, and a method for manufacturing a nerve cell, a complex containing a biotin tagged at the C-terminus of the polypeptide, an artificial synapse inducer for coupling the composite to a streptavidin (SAV)-coated substrate and a nerve cell. The complex tagged with a biotin at the C-terminus of the polypeptide containing the extracellular domain of the synaptogenic protein, such as neuroligin-1, can display activity by being attached to the SAV-coated substrate to adjust the orientation thereof without help of a supported lipid bilayer. The complex containing an additional RFP between the extracellular domain and the biotin of the synaptogenic protein not only facilitates easier mass-production, quantification, and tracking, but also displays activity of a normal synaptogenic protein, thereby inducing excitatory or inhibitory synaptic differentiation by being fixed to the substrate and added to the nerve cell culture.
