Summary: Predicted to enable several functions, including cell adhesion molecule binding activity; identical protein binding activity; and neurexin family protein binding activity. Involved in several processes, including positive regulation of protein localization; presynapse organization; and regulation of synapse assembly. Acts upstream of or within synapse organization. Located in several cellular components, including dendritic shaft; inhibitory synapse; and postsynaptic membrane. Is active in GABA-ergic synapse and postsynaptic specialization membrane. Biomarker of sciatic neuropathy and status epilepticus. Orthologous to human NLGN2 (neuroligin 2). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
