Description: |
Voltage-dependent sodium channels are transmembrane (TM) proteins responsible for the depolarising phase of the action potential in mostelectrically excitable cells []. They may exist in 3 states []: the resting state, where the channel is closed; the activated state, where the channel is open; and the inactivated state, where the channel is closed and refractory to opening. Several different structurally and functionally distinct isoforms are found in mammals, coded for by a multigene family, these being responsible for the different types of sodium ion currents found in excitable tissues.There are nine pore-forming alpha subunit of voltage-gated sodium channels consisting of four membrane-embedded homologous domains (I-IV), each consisting of six α-helical segments (S1-S6), three cytoplasmic loops connecting the domains, and a cytoplasmic C-terminal tail. The S6 segments of the four domains form the inner surface of the pore, while the S4 segments bear clusters of basic residues that constitute the channel's voltage sensors [, , ].The SCN5A gene encodes the NaH1 channel and is expressed in cardiac muscle,foetal skeletal muscle and denervated adult skeletal muscle. Mutationsin the SCN5A gene affect the function of NaH1 channels in the heart and areone of the three causes of Long QT syndrome, an inherited cardiac arrhythmiathat can cause abrupt loss of consciousness, seizures and sudden death []; it is also associated with Brugada syndrome []and conduction systemdisease []. |

Protein Domain |
Type: |
Family |
Description: |
The voltage-sensitive sodium channel consists of an ion conducting pore forming alpha-subunit regulated by one or more non-pore-forming beta subunits. There are five different beta-subunit proteins (beta-1, beta-1B, beta-2, beta-3, and beta-4) encoded by four genes (SCN1B-SCN4B; beta-1B is a splice variant of SCN1B) [, ]. Beta-subunits modulate the kinetics and voltage dependence of the alpha-subunits and they also affect the voltage-gated potassium channels. These subunits participate in nonconducting roles, including cell-cell and cell-matrix adhesion, directing neuronal proliferation, migration, and fasciculation, and modulating the effects of pharmacological compounds on voltage-gated sodium channels, playing important roles in development and disease [, ].Subunit beta-1 is crucial in the assembly, expression, and functional modulation of the sodium channel that can modulate multiple alpha subunit isoforms from brain, skeletal muscle, and heart [, ]. Both beta-1 and beta-3 associate with neurofascin through their extracellular immunoglobulin-like domains. This association may target the sodium channels to the nodes of Ranvier of developing axons and retain these channels at the nodes in mature myelinated axons [].This family represents the beta-1 subunit which modulates the activity of multiple pore-forming alpha subunits, such as SCN1A, SCN2A, SCN3A, SCN4A, SCN5A and SCN10A. It plays a critical role in neuronal migration and pathfinding during brain development, and its function is dependent on Na+ current and gamma-secretase activity [, ]. Alterations in this subunit cause epilepsy and cardiac arrhythmia []. Deletion of SCN1B results in Dravet Syndrome, a severe pediatric encephalopathy characterised by epilepsy development [, ]. The D25N mutation in this subunit causes generalised epilepsy with febrile seizure plus type 1 (GEFS+), leading to a maturation (glycosylation) defect of the protein which impairs its targeting to the plasma membrane and interaction with alpha subunits [, ]. |
