Summary: Enables PDZ domain binding activity. Involved in several processes, including chemical synaptic transmission; nervous system development; and synapse organization. Acts upstream of or within glutamatergic neuron differentiation and neuron projection development. Located in excitatory synapse; juxtaparanode region of axon; and membrane. Part of voltage-gated potassium channel complex. Is active in several cellular components, including axon initial segment; cerebellar granule cell to Purkinje cell synapse; and presynaptic active zone membrane. Is expressed in central nervous system; neural retina; and sciatic nerve. Used to study autism spectrum disorder and cortical dysplasia-focal epilepsy syndrome. Human ortholog(s) of this gene implicated in several diseases, including autism spectrum disorder (multiple); communication disorder (multiple); cortical dysplasia-focal epilepsy syndrome; major depressive disorder; 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.
