SCN5A Antibodies

Scn5a is an integral membrane protein and tetrodotoxin-resistant voltage-gated sodium channel subunit. Scn5a is found primarily in cardiac muscle and is responsible for the initial upstroke of the action potential in an electrocardiogram. Defects in Scn5a are a cause of long QT syndrome type 3 (LQT3), an autosomal domit cardiac disease. Alternative splicing results in several transcript variants encoding different isoforms of Scn5a. Voltage-gated sodium channesl (VGSCs) mediate regenerative cell membrane depolarization and conduction of electrical signalling in nerves and muscles. Expression of Scn5a is also detected in lymphocytes, glia, and fibroblasts. Further, Scn5a mediates ...
