The NRXN2 gene (Neurexin 2) encodes a presynaptic cell adhesion molecule essential for synaptic transmission. Neurexins are a family of transmembrane proteins that interact with postsynaptic neuroligins to form functional synaptic connections. NRXN2 is crucial for excitatory synapse function and is implicated in neurodevelopmental and neurodegenerative disorders.
