Summary: Predicted to enable sodium channel regulator activity and voltage-gated sodium channel activity involved in cardiac muscle cell action potential. Predicted to be involved in several processes, including cardiac muscle cell action potential; regulation of atrial cardiac muscle cell membrane depolarization; and regulation of heart rate by cardiac conduction. Predicted to act upstream of or within regulation of ion transmembrane transport and sodium ion transport. Predicted to be located in membrane. Predicted to be integral component of membrane. Predicted to be part of voltage-gated sodium channel complex. Predicted to be active in plasma membrane. Is expressed in several structures, including cranial ganglion and dorsal root ganglion. Human ortholog(s) of this gene implicated in familial atrial fibrillation. Orthologous to human SCN2B (sodium voltage-gated channel beta subunit 2).

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.
