Summary: Enables protease binding activity and transmembrane transporter binding activity. Involved in prepulse inhibition. Located in several cellular components, including main axon; neuronal cell body; and synaptic membrane. Is active in GABA-ergic synapse; glutamatergic synapse; and presynaptic membrane. Used to study autism spectrum disorder and visual epilepsy. Human ortholog(s) of this gene implicated in several diseases, including Pitt-Hopkins syndrome; autism spectrum disorder (multiple); communication disorder (multiple); cortical dysplasia-focal epilepsy syndrome; and social phobia. Orthologous to human CNTNAP2 (contactin associated protein 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.
