Summary
Predicted to enable sodium ion binding activity and voltage-gated sodium channel activity. Acts upstream of or within several processes, including adult walking behavior; muscle organ development; and sensory perception of sound. Located in several cellular components, including Z disc; neuronal cell body; and node of Ranvier. Part of sodium channel complex. Is expressed in several structures, including heart; metanephros; nervous system; and nucleus pulposus. Used to study early infantile epileptic encephalopathy and epilepsy. Human ortholog(s) of this gene implicated in benign familial neonatal epilepsy and developmental and epileptic encephalopathy 13. Orthologous to human SCN8A (sodium voltage-gated channel alpha subunit 8). [provided by Alliance of Genome Resources, Apr 2022]

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.
