Anti-pan Sodium Channel 抗体 (ab53724)

The pan sodium ion channel, SCN5A, is a cardiac sodium channel distinct from those in nerve and muscle. It is a tetrodotoxin-resistant Na(+) channel isoform. SCN5A mediates the voltage-dependent sodium ion permeability of excitable membranes by opening or closing in response to the voltage difference across the membrane. Na(+) ions pass in accordance with their electrochemical gradient. This channel is responsible for the initial upstroke of the action potential in the electrocardiogram. Defects in SCN5A are involved in many diseases including: progressive familial heart block type I (PFHBI), also known as Lenegre-Lev disease or progressive cardiac conduction defect (PCCD); long QT syndrome type 3 (LQT3); Brugada syndrome; sick sinus syndrome 1 (SSS1); idiopathic ventricular fibrillation (IVF), also called paroxysmal familial ventricular fibrillation; sudden infant death syndrome (SIDS); familial atrial standstill and dilated cardiomyopathy 1E (CMD1E).
