Summary: Enables scaffold protein binding activity; ubiquitin protein ligase binding activity; and voltage-gated sodium channel activity involved in SA node cell action potential. Involved in sodium ion transmembrane transport. Acts upstream of or within cardiac ventricle development; regulation of heart contraction; and response to organic cyclic compound. Located in several cellular components, including T-tubule; intercalated disc; and lateral plasma membrane. Part of sodium channel complex. Is expressed in several structures, including central nervous system; gut; heart; sensory organ; and skeleton. Used to study Brugada syndrome 1; dilated cardiomyopathy 1E; long QT syndrome 3; progressive familial heart block type IA; and sick sinus syndrome. Human ortholog(s) of this gene implicated in heart conduction disease (multiple); intrinsic cardiomyopathy (multiple); and sudden infant death syndrome. Orthologous to human SCN5A (sodium voltage-gated channel alpha subunit 5). [provided by Alliance of Genome Resources, Oct 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.

NM_001253860.1 → NP_001240789.1 sodium channel protein type 5 subunit alpha isoform 2

See identical proteins and their annotated locations for NP_001240789.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) switches an exon in the coding region, compared to variant 1. The resulting protein (isoform 2) is the same length as isoform 1 yet it has a different sequence.
