Summary: Predicted to enable SH3 domain binding activity. Involved in several processes, including cell-cell junction organization; protein localization to axon; and synapse organization. Acts upstream of or within neuron projection development. Located in paranode region of axon and septate junction. Is active in glutamatergic synapse. Is expressed in optic nerve; sciatic nerve; and spinal cord. Human ortholog(s) of this gene implicated in lethal congenital contracture syndrome. Orthologous to human CNTNAP1 (contactin associated protein 1). [provided by Alliance of Genome Resources, Nov 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.
