NLGN2 (Neuroligin 2) is a Protein Coding gene. Among its related pathways are Cell adhesion molecules (CAMs) and Protein-protein interactions at synapses. NLGN2 encodes a member of a family of neuronal cell surface proteins. Members of this family may act as splice site-specific ligands for beta-neurexins and may be involved in the formation and remodeling of central nervous system synapses.
