Function: This protein mediates the voltage-dependent sodium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a sodium-selective channel through which Na(+) ions may pass in accordance with their electrochemical gradient (PubMed:1309946, PubMed:21447824, PubMed:25370050, PubMed:23420830, PubMed:23085483, PubMed:26279430, PubMed:26392562, PubMed:26776555). It is a tetrodotoxin-resistant Na(+) channel isoform (PubMed:1309946). This channel is responsible for the initial upstroke of the action potential. Channel inactivation is regulated by intracellular calcium levels (PubMed:19074138).

Post Translational Modifications: Ubiquitinated by NEDD4L; which promotes its endocytosis. Does not seem to be ubiquitinated by NEDD4 or WWP2.Phosphorylation at Ser-1503 by PKC in a highly conserved cytoplasmic loop slows inactivation of the sodium channel and reduces peak sodium currents (Probable). Regulated through phosphorylation by CaMK2D (By similarity).Lacks the cysteine which covalently binds the conotoxin GVIIJ. This cysteine (position 868) is speculated in other sodium channel subunits alpha to be implied in covalent binding with the sodium channel subunit beta-2 or beta-4.

Subcellular Location: Cell membrane>Multi-pass membrane protein. Cytoplasm>Perinuclear region. Cell membrane>Sarcolemma>T-tubule. Note: RANGRF promotes trafficking to the cell membrane.

Tissue Specificity: Found in jejunal circular smooth muscle cells (at protein level). Expressed in human atrial and ventricular cardiac muscle but not in adult skeletal muscle, brain, myometrium, liver, or spleen. Isoform 4 is expressed in brain.

Subunit Structure: Interacts with the PDZ domain of the syntrophin SNTA1, SNTB1 and SNTB2 (By similarity). Interacts with NEDD4, NEDD4L, WWP2 and GPD1L (PubMed:15217910, PubMed:15548568, PubMed:19666841). Interacts with CALM (PubMed:21167176, PubMed:22705208, PubMed:25370050). Interacts with FGF13; the interaction is direct and FGF13 may regulate SNC5A density at membranes and function (PubMed:21817159, PubMed:22705208, PubMed:26392562). May also interact with FGF12 and FGF14 (PubMed:26392562). Interacts with the spider Jingzhaotoxin-I (AC P83974, AC B1P1B7, AC B1P1B8) (PubMed:26721415). Interacts with ANK3 (PubMed:15579534).

Similarity: The sequence contains 4 internal repeats, each with 5 hydrophobic segments (S1, S2, S3, S5, S6) and one positively charged segment (S4). Segments S4 are probably the voltage-sensors and are characterized by a series of positively charged amino acids at every third position.The IQ domain mediates association with calmodulin.Belongs to the sodium channel (TC 1.A.1.10) family. Nav1.5/SCN5A subfamily.

NCBI Description

The protein encoded by this gene is an integral membrane protein and tetrodotoxin-resistant voltage-gated sodium channel subunit. This protein is found primarily in cardiac muscle and is responsible for the initial upstroke of the action potential in an electrocardiogram. Defects in this gene are a cause of long QT syndrome type 3 (LQT3), an autosomal dominant cardiac disease. Alternative splicing results in several transcript variants encoding different isoforms.
