SCN3B蛋白背景综述

SCN3B (sodium channel, voltage-gated, type III, beta ,human IgG1-Fc chimera) belongs to the sodium channel auxiliary subunit SCN3B (TC 8.A.17) family. It contains 1 Ig-like C2-type (immunoglobulin-like) domain. SCN3B modulates channel gating kinetics; causes unique persistent sodium currents; inactivates the sodium channel opening more slowly than the subunit beta-1. Its association with neurofascin may target the sodium channels to the nodes of ranvier of developing axons and retain these channels at the nodes in mature myelinated axons. Defects in SCN3B are the cause of Brugada syndrome type 7. A tachyarrhythmia characterized by right bundle branch block and ST segment elevation on an electrocardiogram. It can cause the ventricles to beat so fast that the blood is prevented from circulating efficiently in the body. When this situation occurs (called ventricular fibrillation), the individual will faint and may die in a few minutes if the heart is not reset.
