SCN10A Membrane Protein Introduction

Introduction of SCN10A

Sodium channel protein type 10 subunit alpha protein (SCN10A) encoded by the SCN10A gene is a tetrodotoxin-resistant voltage-gated sodium channel alpha subunit. The protein contains 1956 amino acids, and molecular mass of the protein is 220 kDa. The sequence has 4 internal repeats, each with 5 hydrophobic segments (S1, S2, S3, S5, S6) and one positively charged segment (S4). S4 may be a voltage sensor characterized by a series of positively charged amino acids at every three positions. SCN10A is expressed in the dorsal root ganglia and sciatic nerve. The channel consists of an ion-conducting pore forming alpha-subunit regulated by one or more associated auxiliary subunits SCN1B, SCN2B and SCN3B; electrophysiological properties may vary depending on the type of the associated beta subunits.

Function of SCN10A Membrane Protein

SCN10A mediates the voltage-dependent sodium ion permeability of excitable membranes. Assuming that in response to a voltage difference across the membrane, the conformation is turned on or off, and then, the protein forms a sodium-selective channel through which sodium ions can pass according to their electrochemical gradient. SCN10A may play a role in peripheral neuropathic pain mechanisms. Alternative splicing results in multiple transcript variants. Diseases associated with SCN10A include episodic pain syndrome, atrial fibrillation, and Brugada syndrome. These diseases are caused by mutations that affect SCN10A expression.

This article suggests that SCN10A greatly improves our ability to genotype and risk stratify probands and family members.
Jabbari J., et al. Common and rare variants in SCN10A modulate the risk of atrial fibrillation. Circulation-Cardiovascular Genetics. 2015, 8(1):64-73. PubMed ID: 25691686

This article reveals that rare and common variants of SCN10A have an effect on the function of the channel, indicating that these variants influence susceptibility to atrial fibrillation.
