Summary: Enables cadherin binding activity; calcium ion binding activity; and identical protein binding activity. Involved in cell-cell adhesion and neural tube formation. Acts upstream of or within several processes, including brain morphogenesis; excitatory postsynaptic potential; and regulation of neuronal action potential. Located in plasma membrane. Is expressed in several structures, including brain; eye; immature eye; posterior neural keel; and spinal cord. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 9. Orthologous to human PCDH19 (protocadherin 19). [provided by Alliance of Genome Resources, Jul 2025]

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.
